Presto 08810 Pro Electric Knife Sharpener

For some, a manual knife sharpener isn’t an option. This could be due to arthritic hands, injuries or just lack of convenience. Maybe you have a very busy schedule and you need to spend your time in the kitchen cooking not sharpening or you need to be out in the field hunting not in the shed sharpening your hunting knife.

Presto Professional Electric Knife Sharpener uses a three stage sharpening system. If your knife is very dull, you will probably use all three stages.

If you knife merely needs a touch up then two of the stages (2 and 3 – medium and honing) will be used. And, most frequently, only the third stage, the honing stage is needed to maintain your knives to the perfect razor sharp condition.

The blade selector adjusts the blade guides to an optimum sharpening angle for thick (hunting knives and cleavers), medium (utility, slicing, chef’s, and Santoku knives), and thin (fillet, paring knives, and other light blades) knives.

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 or yard tools.

If your blade is very dull or if you are sharpening the knife for the first time, begin with STAGE 1 – COARSE GRINDING. This stage uses a sapphirite coarse grinding wheel (a toughened mineral glass coated with a layer of sapphire glass). This creates the first proper blade angle.

Stage 1 is the coarsest and most aggressive stage, and it will remove more material from the knife blade than the other stages.

Note that it is a fixed stage with no adjustments, as it places the same angle on all blades in preparation for the sharpening stations found in Stages 2 and 3.

This can be thought of as the back bevel of a compound double bevel – don’t know what I mean?  Then check out our paper on the different knife edges.

Stage 2 can be used for your routine sharpening tasks and is less coarse than Stage 1.

Stage 2, continues the process using another sapphirite wheel in medium grit for a precision edge. If your knife is just a bit dull, begin with STAGE 2 – MEDIUM GRINDING followed by Stage 3.

If your knife just needs a little touch-up sharpening, begin with STAGE 3 – FINE HONING. It completes the knife sharpening process or touches up your knife by honing and polishing the knife to an exact razor-sharp edge. This will be the stage most often used.

The Presto 08810 has a very user-friendly design feature called the ‘No Guess Sharpening’. The sharpener has three adjustable blade selector settings – thick, medium and sharp.

  • Thick – used for hunting knives, cleavers etc.
  • Medium – used for Chef’s knives and standard kitchen knives etc.
  • Thin – used for light blades such as fillet and paring knives.

Adjust the selector settings and place the blade through the appropriate slot then, using only light downward pressure, slowly pull the knife towards you. That’s it. The automatic blade angle adjuster will hold the knife at the correct angle to the grinding wheel, making this a truly ‘no guess’ sharpener!

Pros and Cons

The Presto Professional Electric Knife Sharpener got some great reviews at Amazon..

I would highly recommend practicing on a couple knives too.  The other key idea that was mentioned was to be sure to use Stage 1 sparingly since it does remove the most metal from your knife blades.

No matter your sharpening needs, it seems that the Presto 08810 Professional Electric Knife Sharpener has your back and, no guessing!
