Smith’s Adjustable Manual Knife Sharpener has an Adjustable Angle feature and offers new, innovative features never before used on a manual knife sharpener and functional performance unmatched by standard edge maintenance products or companies.

This is a super unique design in a manual pull-through sharpener that makes this a huge bargain. The ability to change the angle of the sharpening stones makes this rival other more expensive sharpeners.

The two stages of sharpening (Coarse and Fine) for all types of straight edge knives with a grind on both sides of the blade.

It is very important to use the right stage for your knife sharpening tasks.

Stage 1 is used for excessively worn, dull, or damaged knives. Stage 1 has the coarsest 100% diamond coated discs and will remove the most metal so you should only use this stage when it is truly needed. It is definitely okay to remove metal and that is really what sharpening is all about but remove no more metal than is needed.

There is also a fixed-angle slot for sharpening serrated edge blades. It will sharpen a variety of knives by simply adjusting the angle of the abrasive components to match the angle of the original factory grind. Just turn the dial to one of the 6 angles offered, then pull your knife through the appropriate slot(s).

If you are unsure of the proper knife angle for your knife, suggested angles are printed on the unit. There’s really no way to go wrong with this knife sharpener.
