Most everyday kitchen knives use a plain double-bevel edge, often called a V-edge, or a compound double bevel with a tiny microbevel at the very edge. That is the normal edge on many chef’s knives, paring knives, utility knives, and knife-block sets.
Other knives need different treatment. Serrated bread knives, traditional single-bevel Japanese knives, convex edges, hollow grinds, heavy cleavers, and Granton-style or scalloped slicing blades all cut differently and should not all be sharpened the same way.
The best knife edge type is not universal. Edge geometry changes cutting feel, food release, durability, and sharpening method. A tomato knife, a gyuto, a meat cleaver, and a bread knife are not trying to solve the same kitchen problem.
This guide clears up the confusing knife language: edge, apex, bevel, grind, microbevel, serration, and scallop. If you are trying to choose an exact sharpening angle, use our knife sharpening angle guide. This page is about edge shape and edge geometry.

Knife Edge Types at a Glance
Use this table as the quick version. The sections below explain what each edge looks like, why it cuts the way it does, and how to maintain it without damaging the knife.
| Edge / blade feature | What it looks like | Common kitchen uses | Strengths | Watch-outs | Sharpening note |
|---|---|---|---|---|---|
| Plain V-edge / double bevel | Two angled bevels meet at the apex | Chef’s knives, paring knives, utility knives | Common, versatile, easy to maintain | Still needs the right angle for the knife | Works with whetstones, guided sharpeners, and compatible electric sharpeners |
| Compound edge / microbevel | A main bevel with a tiny second bevel at the edge | Chef’s knives, Japanese-style knives, harder-use kitchen knives | Improves durability and makes touch-ups easier | Easy to overdo if you use too much pressure | Use controlled final passes at a slightly higher angle |
| Chisel edge / single bevel | One main sharpened side and one flatter back side | Traditional yanagiba, deba, usuba, some specialty knives | Very precise slicing and food separation | Right- and left-handed geometry matters | Do not sharpen like a standard double-bevel knife |
| Convex edge | Rounded shoulders curve into the apex | Some outdoor knives, specialty kitchen knives, custom edges | Smooth cutting feel and more support behind the edge | Harder to preserve with standard sharpeners | Often maintained with stropping or careful freehand work |
| Hollow edge / hollow grind | Concave sides curve inward toward the edge | Razors, some pocket knives, some thin cutting tools | Can feel very keen and low-friction | Less support behind the apex if too thin | Sharpen based on the actual edge bevel, not only the grind name |
| Serrated edge | Teeth and gullets along the cutting edge | Bread knives, tomato knives, steak knives | Grips crusts, skins, and slippery foods | Not sharpened like a plain-edge knife | Use a tapered ceramic rod, serration tool, or professional service |
| Granton-style / cullen / scalloped blade | Scallops or grooves on the blade face, not teeth on the edge | Slicers, santokus, carving knives, cheese and salmon knives | Helps with food release and sticking | Often confused with serrations | Sharpen the actual cutting edge normally; do not grind the scallops |
| Scandi edge | Large flat bevel runs directly to the edge | Outdoor and woodcraft knives more than kitchen knives | Easy to follow on a stone and strong behind the edge | Not the default geometry for kitchen prep knives | Use the bevel as the guide if the knife is truly Scandi |
| Heavy cleaver edge | Thicker, stronger edge with more steel behind it | Meat cleavers and chopping knives | Durable for impact and rougher work | Not a fine slicing edge | Use a stronger angle; avoid converting to a thin 15° slicer edge |
Identify Your Knife Edge
Use this tool as a practical starting point. Choose what the cutting edge looks like, how many sides are sharpened, whether you see scallops on the blade face, the knife type, and the maintenance tool you plan to use. It will estimate the likely edge type and suggest the safest maintenance approach.
This tool is not a replacement for manufacturer guidance. If the knife is expensive, single-bevel, serrated, chipped, or unfamiliar, confirm the edge geometry before sharpening or use a professional sharpening service.

Knife Edge Anatomy: Edge, Apex, Bevel and Grind
Knife people do not always use “primary bevel” and “secondary bevel” the same way. In this guide, we define the terms before using them.
- Edge: The cutting part of the knife. In casual use, people often use “edge” to mean the bevel, the apex, or the whole cutting geometry.
- Apex: The very point where the cutting sides meet. If the apex is rounded, the knife feels dull even if the rest of the blade looks fine.
- Bevel: The angled surface that forms the edge. A double-bevel knife has a bevel on both sides.
- Primary bevel: In this guide, the larger bevel or thinning surface leading toward the edge.
- Secondary bevel: In this guide, the smaller bevel closer to the apex, often the part you actually sharpen.
- Microbevel: A very small secondary bevel right at the apex, often used to add durability or make touch-ups easier.
- Burr: A tiny wire-like fold of metal that can form during sharpening. Removing the burr is part of getting a clean edge.
- Blade face: The broad side of the knife above the bevel.
- Grind: The way the blade thins from the spine or blade face toward the edge.
- Spine: The top, non-cutting edge of the blade.
- Edge angle: The sharpening angle on one side of the edge.
- Inclusive angle: The total angle of both sides together on a double-bevel knife.
Quick direction: If you are trying to choose an actual sharpening angle, use the knife sharpening angle guide. This page is mainly about edge shape and edge geometry.
Edge Type vs. Blade Grind
This is where knife language gets messy. The edge type describes the cutting edge and bevel near the apex. The blade grind describes how the blade thins from the spine or blade face toward the edge.
A knife can have a full flat grind and still finish in a small V-edge at the apex. A Granton-style blade can still have a plain edge. A serrated edge is different from a scalloped blade face. A convex grind can run all the way to the edge, or a knife can have a convexed shoulder with a microbevel depending on how it was made or sharpened.
| Term | What it means | Where you see it | Why it matters |
|---|---|---|---|
| V-edge | Two bevels meet in a V shape at the apex | Most kitchen knives | Versatile and easy to sharpen |
| Double bevel | Both sides of the blade are sharpened | Chef’s knives, santokus, paring knives | Works for right- and left-handed users |
| Single bevel | One main side is sharpened more than the other | Traditional Japanese yanagiba, deba, usuba | Precise but side-specific and technique-sensitive |
| Microbevel | Tiny bevel at the apex | Many maintained kitchen knives | Adds durability and simplifies touch-ups |
| Full flat grind | Blade tapers broadly and evenly toward the edge | Many chef’s knives and general-purpose knives | Can reduce wedging and improve slicing |
| Hollow grind | Blade sides curve inward | Razors, pocket knives, some thin blades | Can feel keen but may need careful maintenance |
| Convex grind | Blade sides curve outward toward the edge | Outdoor knives, axes, some specialty knives | Can provide edge support and smooth cutting |
| Scandi grind | Large flat bevel runs to the edge | Outdoor, carving, and woodcraft knives | Easy to follow on a stone, but not a default kitchen grind |
| Granton-style / cullen scallops | Grooves or scallops on the blade face | Slicers, santokus, carving knives | Helps food release; not the same as serrations |
| Serrations | Teeth and gullets on the cutting edge | Bread knives, tomato knives, steak knives | Grips crusty or slippery food, but needs special sharpening |
For a visual primer on blade grinds, A.G. Russell’s blade grinds guide is useful background. Just remember that kitchen knife marketing often mixes terms, so always look at the actual edge before choosing a sharpener.
The Main Knife Edge Types
Plain V-Edge / Double-Bevel Edge
What it looks like: A plain V-edge has two angled bevels that meet at the apex. If you looked at the edge in cross-section, it would look like a small V.
Where you’ll find it: Most home kitchen knives use some version of this edge: chef’s knives, paring knives, utility knives, boning knives, many santokus, and many nakiris sold for home kitchens.
Why it cuts the way it does: The apex starts the cut, while the bevel and blade thickness decide how much the food has to spread apart. A thin V-edge slices easily. A thick V-edge may feel sturdy but can wedge in carrots, squash, or dense food.
Strengths: It is common, predictable, easy to identify, and compatible with many sharpening tools.
Weaknesses: A V-edge is not automatically durable. A very low-angle V-edge on soft steel can roll quickly, while a thick V-edge can feel dull even when the apex is sharp.
How to maintain or sharpen it: Match the factory angle when possible. Use a whetstone, guided sharpener, or compatible electric sharpener. Our guide to the best knife sharpeners is the next stop if you are choosing a tool.
Best for: Everyday kitchen prep, general chef’s knives, beginner sharpening practice, and mixed knife blocks.
Avoid for: Bread crusts, heavy bone chopping, and specialty single-bevel work.
Compound Edge / Double Bevel / Microbevel
What it looks like: A compound edge can look like a large V with a tiny second V at the apex. The small final bevel is often called a microbevel.
Where you’ll find it: You may find compound edges on factory knives, maintained Japanese-style knives, pocket knives, and kitchen knives that have been touched up at a slightly higher angle than the main bevel.
Why it cuts the way it does: The thin primary geometry helps the knife enter food, while the small microbevel adds support at the apex. It is a practical compromise between sharpness and durability.
Strengths: A microbevel can make an edge easier to maintain. Instead of grinding the whole bevel every time, you refresh a tiny strip of steel at the apex.
Weaknesses: The terminology is confusing. “Double bevel” can simply mean sharpened on both sides, while “compound bevel” means the edge has more than one bevel angle. Do not assume every double-bevel knife has a compound edge.
How to maintain or sharpen it: Use a whetstone or guided sharpener with controlled final passes. A common approach is to sharpen the main bevel, then add a few very light strokes at a slightly higher angle to create the microbevel.
Best for: Cooks who want an edge that slices well but holds up better in daily kitchen use.
Avoid for: Guesswork sharpening. If you keep adding higher-angle passes without thinning behind the edge, the knife can eventually feel thick and wedgy.
Chisel Edge / Single-Bevel Edge
What it looks like: A chisel edge is asymmetric. One side has the main bevel, while the other side is flatter or has a very subtle back bevel depending on the knife.
Where you’ll find it: True single-bevel geometry is common on traditional Japanese knives such as yanagiba, deba, and usuba. Some specialty knives use it too.
Important correction: Do not assume every santoku or nakiri is single bevel. Many santoku and nakiri knives sold to home cooks in the United States and Europe are double-bevel knives.
Why it cuts the way it does: A single-bevel knife can make very precise cuts and can help steer or release slices in a particular direction. That is useful for raw fish, delicate vegetable work, and traditional Japanese techniques.
Strengths: Excellent precision when used for the right task by someone who understands the geometry.
Weaknesses: Right-handed and left-handed versions matter. The wrong geometry can feel awkward or steer through food. Sharpening mistakes can change the knife dramatically.
How to maintain or sharpen it: Do not sharpen it like a normal double-bevel chef’s knife. Use correct single-bevel technique or a professional sharpening service. For tool ideas, see our guide to the best Japanese knife sharpener.
Best for: Traditional sushi, sashimi, Japanese vegetable work, and specialized slicing tasks.
Avoid for: Casual pull-through sharpeners, generic electric sharpeners, and rough kitchen work unless the tool specifically supports single-bevel knives.
Convex Edge
What it looks like: A convex edge has rounded shoulders that curve into the apex. Instead of flat bevels forming a sharp V, the sides bulge outward slightly.
Where you’ll find it: Convex edges are common in outdoor and chopping tools, some custom knives, some premium edges, and knives maintained by sharpeners who intentionally convex the shoulders.
Why it cuts the way it does: The rounded shoulder can move through material smoothly while keeping more steel behind the apex. That extra support can help durability.
Strengths: A convex edge can feel smooth through cuts and can be tougher than an equally thin flat V-edge.
Weaknesses: A true convex edge is harder to maintain with fixed V-slot sharpeners. Many sharpeners will slowly turn it into a flatter V-edge over time.
How to maintain or sharpen it: Use stropping, careful freehand sharpening, flexible backing, a belt system, or a sharpener designed to preserve convex geometry. Do not assume every home sharpener can maintain it.
Best for: Tougher work, outdoor knives, some cleaver-like tools, and users who value edge support.
Avoid for: People who want the easiest possible sharpening setup with standard angle slots.
Hollow Edge / Hollow Grind
What it looks like: A hollow grind curves inward toward the edge. In cross-section, the sides look concave instead of flat or rounded outward.
Where you’ll find it: Razors are the obvious example. You can also see hollow grinds on some pocket knives, outdoor knives, and specialty cutting tools. Some kitchen marketing uses “hollow edge” to describe scalloped blade-side reliefs, so inspect the blade carefully.
Why it cuts the way it does: A hollow grind can get very thin behind the apex, which can make the edge feel keen. But if there is not enough support behind the cutting edge, it can be more delicate.
Strengths: Low resistance at the edge and a very sharp cutting feel when the geometry fits the job.
Weaknesses: Less support behind the apex depending on the blade thickness and grind. It may not be ideal for hard board contact or impact.
How to maintain or sharpen it: Sharpen the actual edge bevel. Do not change the blade geometry casually just because the grind is hollow.
Best for: Fine cutting tools and knives designed around that geometry.
Avoid for: Heavy chopping, twisting, scraping, and rough kitchen work.
Serrated Edge
What it looks like: A serrated edge has teeth and gullets along the cutting edge itself. The teeth grip the food, while the recessed cutting surfaces do much of the slicing.
Where you’ll find it: Bread knives, tomato knives, steak knives, and some utility knives.
Why it cuts the way it does: Serrations act like tiny saw teeth. They bite into crusty bread, tomato skin, sausage casing, citrus peel, and other surfaces that can slip under a plain edge.
Strengths: Serrated knives are excellent for foods with a tough outside and soft inside. They also tend to keep working longer because much of the cutting edge sits recessed above the cutting board.
Weaknesses: Serrated knives are harder to sharpen evenly. They are not good for clean push cuts, mincing, or board-heavy chopping.
How to maintain or sharpen it: Do not run a serrated knife through a standard plain-edge pull-through sharpener. Use a tapered ceramic rod, serration-specific tool, or professional service. Sharpen each gullet from the beveled side and remove burrs carefully.
Best for: Bread, tomatoes, citrus, cakes, and foods that need grip before slicing.
Avoid for: Fine knife work, chef’s-knife tasks, and electric sharpeners not designed for serrations.
Granton-Style / Cullen / Scalloped Blade
What it looks like: A Granton-style, cullen, or scalloped blade has grooves or dimples along the blade face. These scallops are not teeth on the cutting edge.
Where you’ll find it: Slicing knives, carving knives, santokus, cheese knives, salmon knives, and some chef’s knives.
Why it cuts the way it does: The scallops can create small pockets between the blade and the food, which may help slices release instead of clinging to the blade. This can be useful with moist or sticky foods.
Terminology note: Granton® is associated with Granton Knives. Many other brands use terms like “Granton-style,” “hollow edge,” “cullen,” or “scalloped” to describe similar blade-side food-release features. Granton’s own explanation of the feature is here: Granton Edge.
Strengths: Helps with food release when slicing salmon, cheese, cucumbers, potatoes, meats, and other foods that can stick to a broad blade face.
Weaknesses: The feature is often oversold. It helps with sticking, but it does not turn a dull knife into a sharp one.
How to maintain or sharpen it: Sharpen the actual cutting edge normally if it is a plain edge. Do not grind into the scallops on the blade face.
Best for: Thin slicing, carving, cheese, salmon, cucumbers, potatoes, and sticky foods.
Avoid for: Treating it like a serrated edge. It is a food-release blade feature, not a row of cutting teeth.
Heavy Cleaver Edge
What it looks like: A heavy cleaver edge is usually thicker and more durable than a fine slicing edge. There is more steel behind the apex.
Where you’ll find it: Meat cleavers and chopping knives designed for impact. This is different from a Chinese vegetable cleaver, which may be thin and slicey.
Why it cuts the way it does: A heavy cleaver edge trades clean slicing for impact resistance. The stronger geometry helps the edge survive chopping and harder contact.
Strengths: Durable and appropriate for rougher chopping tasks when the knife is designed for them.
Weaknesses: It will not glide through onions, herbs, or tomatoes like a thin chef’s knife. A thick edge wedges more.
How to maintain or sharpen it: Use a durable angle and avoid thinning it into a delicate 15° slicing edge unless the knife is actually a vegetable cleaver designed for slicing.
Best for: Heavier chopping and rougher work within the knife maker’s intended use.
Avoid for: Fine slicing, delicate vegetables, and precision prep.
Scandi Edge, as a Contrast Example
What it looks like: A Scandi grind has a large flat bevel that runs directly to the edge, often without a tiny secondary bevel.
Where you’ll find it: Outdoor, bushcraft, carving, and woodcraft knives more often than kitchen knives.
Why it cuts the way it does: The big flat bevel can act as its own angle guide on a stone, which makes the geometry easy to follow. It also leaves plenty of material behind the edge.
Strengths: Strong, easy to understand visually, and useful for carving or controlled outdoor cuts.
Weaknesses: It is not the default geometry for most kitchen prep knives and can feel wedgy in dense vegetables if the blade is thick.
How to maintain or sharpen it: If the knife is truly Scandi, use the bevel as the guide on the stone. Do not assume a kitchen knife is Scandi just because it has a visible bevel.
Best for: Outdoor knives, carving, and contrast learning.
Avoid for: Treating it as the normal choice for a chef’s knife or santoku.
Which Knife Edge Type Is Best?
The best knife edge type depends on the job. Match the edge to the food and the maintenance method you are actually willing to use.
| Use case | Best edge/feature | Why | What to avoid |
|---|---|---|---|
| Everyday chef’s knife | Plain V-edge or compound edge | Versatile, easy to sharpen, works for most prep | Extreme low-angle edges on soft steel |
| Japanese-style slicing knife | Thin double bevel or true single bevel if designed for it | Clean slicing and lower wedging | Generic pull-through sharpeners |
| Bread knife | Serrated edge | Grips crust without crushing soft bread | Plain-edge chef’s knife for crusty loaves |
| Tomato knife | Serrated or very sharp thin plain edge | Grips slick skin and cuts without smashing | Dull thick edges |
| Carving/slicing knife | Plain edge with Granton-style scallops if sticking is a problem | Long smooth slices and better food release | Serrations unless you want a saw-like cut |
| Santoku for vegetables | Plain double bevel, sometimes with scalloped blade-side reliefs | Good for push cuts and daily prep | Assuming all santokus are single bevel |
| Meat cleaver | Heavy cleaver edge | More support behind the apex for impact | Thin 15° slicing geometry |
| Chinese vegetable cleaver | Thin V-edge or compound edge | Slices vegetables and scoops food | Treating it like a bone cleaver |
| Pocket knife | V-edge, compound edge, convex, or Scandi depending on design | Use case varies from light slicing to rough utility work | Kitchen-only assumptions |
| Hunting/outdoor knife | Convex, compound, or stronger V-edge | Durability matters more than delicate kitchen slicing | Ultra-thin kitchen angles |
| Cheese, salmon, cucumber slicing | Plain edge plus scalloped blade-side reliefs | Food release matters | Confusing scallops with serrations |
| Beginner home cook | Plain V-edge / double bevel | Easiest to identify, sharpen, and maintain | Expensive specialty knives before learning basics |
| Person using an electric sharpener | Compatible plain V-edge or supported compound edge | Preset angle systems work best with compatible knives | Single-bevel, serrated, fragile, or specialty knives unless supported |
How Edge Geometry Changes Cutting Performance
Sharpness is not only about the apex. The apex starts the cut, but the blade geometry decides how easily the food separates after the cut begins.
A thin blade with a fine edge can glide through a tomato because the edge breaks the skin and the blade does not have to push much food apart. A thick wedge-shaped blade can feel dull in a carrot even when the apex is technically sharp, because the carrot has to split around a thicker piece of steel.
- Lower friction: Thin edges and polished bevels can reduce drag.
- Less wedging: Thin blade geometry separates dense food more easily.
- More steel behind the apex: Stronger edges handle impact and rougher use better.
- Food release: Blade shape, scallops, surface finish, and food moisture all affect sticking.
- Edge rolling and chipping: Thin edges can cut beautifully but may fail faster if the steel or use case is wrong.
- Cutting board and technique: Twisting, scraping, glass boards, and hard contact can damage even a well-sharpened edge.
Nerdy Science in the Kitchen: The apex is the first contact point, but the rest of the blade acts like a wedge. A thin blade through a tomato feels effortless because it starts the cut cleanly and does not force the food apart. A thick blade through a carrot can feel dull because the wedge has to spread dense food after the apex enters.
How to Identify the Edge on Your Knife
You can learn a lot with bright light, a steady hand, and a close look at the edge. Do not start sharpening until you know what you are looking at.
- Look at the very edge under bright light. A dull rolled apex often reflects light.
- Check whether both sides are sharpened. If both sides have bevels, it is likely double bevel. If one side dominates, it may be single bevel or asymmetric.
- Look for a tiny secondary bevel or microbevel. It may appear as a narrow shiny line right at the edge.
- Look for serrations and gullets. Serrations are teeth on the cutting edge itself.
- Look for scallops on the blade face. Granton-style or cullen scallops are grooves on the side of the blade, not teeth on the edge.
- Use a marker on the bevel. If you are trying to match the current sharpening angle, color the bevel, make a few light passes, and see where the marker disappears.
- Use a loupe or phone macro lens. Magnification makes microbevels, burrs, and edge damage easier to see.
- Check the manufacturer’s page or manual. This matters most for expensive, Japanese, serrated, and specialty knives.

How to Sharpen Each Edge Type
The safest sharpening method depends on the edge. The wrong tool can erase the geometry that made the knife useful in the first place.
| Edge type | Best sharpening method | Maintenance tool | Avoid | Difficulty |
|---|---|---|---|---|
| V-edge | Whetstone, guided sharpener, compatible electric sharpener | Honing rod or ceramic rod if appropriate | Changing the factory angle by accident | Easy to medium |
| Compound / microbevel | Guided sharpener or whetstone with controlled final passes | Fine stone, ceramic rod, or strop | Repeated high-angle passes without thinning | Medium |
| Chisel / single bevel | Correct single-bevel technique or professional sharpening | Suitable stones and careful back-side maintenance | Standard pull-through and generic electric sharpeners | Hard |
| Convex | Strop, flexible backing, careful freehand, or belt system | Leather strop and compound | Fixed V-slots that flatten the convex shape | Medium to hard |
| Hollow | Depends on actual edge bevel | Fine stone or strop if compatible | Changing blade geometry casually | Medium |
| Serrated | Tapered ceramic rod, serration tool, or professional service | Serration-matched rod | Plain-edge pull-through sharpeners | Medium to hard |
| Granton-style / scalloped blade | Sharpen the plain cutting edge normally | Same as the underlying edge type | Grinding the scallops on the blade face | Depends on edge |
| Heavy cleaver edge | Stone or guided system at a durable angle | Coarser-to-medium stones as needed | Thin slicing geometry | Medium |
| Scandi | Use the bevel as a guide if truly Scandi | Stone and strop | Adding a random microbevel unless intentional | Medium |

Common Knife Edge Mistakes
- Calling blade grind and edge type the same thing. They are related, but not identical.
- Calling Granton-style scallops serrations. Serrations are teeth on the cutting edge. Scallops are usually on the blade face.
- Sharpening single-bevel knives like double-bevel knives. This can damage the geometry.
- Running serrated knives through a standard pull-through sharpener. That can damage the teeth and gullets.
- Converting every knife to 15°. A heavy cleaver and a thin gyuto should not have the same edge goal.
- Ignoring the factory edge. Matching the existing geometry is usually safer than reinventing it.
- Using the same sharpener for every knife. Specialty edges need specialty care.
- Using too much pressure. Heavy pressure removes metal faster and makes angle control worse.
- Not deburring. A leftover burr can make a knife feel sharp briefly, then fail quickly.
- Using a honing rod instead of sharpening when the edge is truly dull. Honing and sharpening are not the same job.
- Scraping food off a board with the cutting edge. Use the spine or a bench scraper instead.
- Using a precision slicer for chopping bones or hard materials. Use the right knife for the task.
Recommended Gear for Different Knife Edges
This is not a product roundup. The right gear depends on the edge type and how much control you need.
- For plain V-edges: A whetstone, guided sharpener, or compatible electric sharpener can work. Start with our best knife sharpeners guide.
- For 15° kitchen knives: Use a sharpener that actually supports that angle. See our 15-degree knife sharpener guide.
- For Japanese-style and single-bevel knives: Use the right stones, technique, or a professional. Start with the best Japanese knife sharpener guide.
- For whetstone work: Learn on a forgiving knife before working on expensive blades. See our best whetstone for kitchen knives guide.
- For pocket knives: The edge may be V, compound, convex, or Scandi depending on the design. See our guide on how to sharpen a pocket knife.
- For serrations: Use a tapered ceramic rod, serration-specific tool, or professional service. Do not use a standard plain-edge slot unless the manufacturer explicitly supports serrated knives.
Knife Edge Types FAQ
What is the most common kitchen knife edge?
The most common kitchen knife edge is a plain double-bevel V-edge. It is found on many chef’s knives, paring knives, utility knives, santokus, and everyday knife-block knives.
What is the difference between a knife edge and a knife grind?
The edge is the cutting geometry near the apex. The grind is how the blade thins from the spine or blade face toward that edge. A knife can have a flat grind and still finish with a small V-edge at the apex.
What is a V-edge knife?
A V-edge knife has two angled bevels that meet at the cutting apex. It is common, versatile, and usually one of the easiest edge types for home cooks to maintain.
What is a double-bevel knife?
A double-bevel knife is sharpened on both sides of the blade. Most everyday kitchen knives are double bevel, including many Western chef’s knives and many Japanese-style knives sold for home use.
What is a compound edge or microbevel?
A compound edge has more than one bevel angle near the edge. A microbevel is a tiny bevel at the apex that can make the edge easier to maintain or more durable.
What is a chisel edge knife?
A chisel edge, or single-bevel edge, is sharpened mainly on one side. It is common on some traditional Japanese knives and specialty tools. It should not be sharpened like a normal double-bevel chef’s knife.
Are santoku knives single bevel or double bevel?
Many santoku knives sold to home cooks are double bevel. Some traditional or specialty Japanese knives are single bevel, but it is not accurate to say all santokus are single bevel. Check the exact knife.
What is a convex edge?
A convex edge has rounded shoulders that curve into the apex. It can provide more support behind the cutting edge, but it is harder to preserve with standard sharpeners.
What is a hollow edge?
A hollow edge or hollow grind has inward-curving, concave geometry. It can feel very keen, but depending on the blade and edge thickness, it may have less support behind the apex.
What is a serrated edge best for?
A serrated edge is best for bread, tomatoes, citrus, cakes, sausage casing, and foods with a tough outside and soft inside. The teeth grip the surface before slicing through it.
Can serrated knives be sharpened?
Yes, serrated knives can be sharpened, but they require a different method than plain-edge knives. Use a tapered ceramic rod, serration-specific tool, or professional sharpening service.
What is a Granton edge or scalloped knife?
A Granton-style or scalloped knife has grooves on the blade face to help food release from the blade. The cutting edge itself may still be a plain edge.
Is a Granton-style blade the same as a serrated knife?
No. A serrated knife has teeth on the cutting edge. A Granton-style or scalloped blade usually has grooves on the blade face and can still have a straight plain edge.
Which knife edge is easiest to sharpen?
A plain double-bevel V-edge is usually the easiest knife edge for home cooks to sharpen because it is common, visible, and compatible with many sharpening methods.
Which edge type should beginners use?
Beginners should start with plain double-bevel knives and learn to match the factory angle. Avoid practicing on expensive single-bevel, serrated, or specialty knives.
Which edge is best for slicing vegetables?
For most vegetables, a sharp plain V-edge or compound edge on a thin chef’s knife, santoku, nakiri, or gyuto works well. Blade thickness matters as much as the edge itself.
Which edge is best for bread?
A serrated edge is best for bread because the teeth grip crust without crushing the soft interior.
Should I change my knife’s edge type?
Usually, no. Match the factory edge unless you understand the tradeoff. Changing edge type can remove a lot of steel and may make the knife worse for its intended job.
Final Takeaway
Knife edge types are not just trivia. They explain why one knife glides through tomatoes, another saws through bread, another releases cucumber slices, and another survives chopping work.
For most home cooks, the practical answer is simple: learn the plain double-bevel V-edge first, match the factory geometry, and use the right maintenance method. Then treat serrated knives, single-bevel knives, convex edges, heavy cleavers, and scalloped blade features as special cases.
The nerdy kitchen truth is that the edge starts the cut, but the whole blade finishes it. Understand the geometry, and you will choose, sharpen, and use your knives with far fewer mistakes.
