This is a countertop electric sharpener that runs a knife through three stages: a coarse diamond wheel that rebuilds a damaged or badly dulled edge, a finer diamond stage that sets the bevel, and a ceramic honing stage that polishes it. The guides hold the blade at a 15-degree angle, which matches Japanese-style knives and the thinner Western knives most home cooks now buy, rather than the 20-degree angle older sharpeners assume. The practical value is that it removes the guesswork of a whetstone: you pull the blade through each slot a few times in order and get a repeatable edge. Best fit: home cooks with a couple of good knives who have been living with dull ones because a whetstone felt like a skill to learn.
Pros
- Three stages cover rebuilding, sharpening, and honing rather than just touching up an edge
- Diamond abrasives cut fast enough to rescue a badly dulled blade
- 15-degree guides suit Japanese-style and thinner Western knives
- Angle guides remove the learning curve a whetstone requires
Cons
- Pull-through sharpeners remove more steel than a whetstone, so a treasured knife will wear faster over years of use

Frequently asked questions
Will this sharpen serrated knives?
No. Pull-through electric sharpeners are for straight edges. Serrated bread knives need a tapered rod that fits between the scallops.
Does it work on Japanese knives?
Yes, that is what the 15-degree angle is for. Very hard Japanese steels above roughly 62 HRC are better handled on a whetstone to avoid chipping.
How many passes does a dull knife need?
Usually a few in the coarse stage, then a few in each following stage. Badly damaged edges need more coarse passes, but check often so you do not remove more steel than necessary.
Can I sharpen scissors with it?
No. The slots are cut for knife blades. Scissors need a different geometry and will not seat correctly.
