Professional Electric Diamond Knife Sharpener, 2 Stage Coarse and Fine with 4 Blade Guide Slots for Correct Angle, with a Non Slip Base

Used this on a couple regular kitchen knives. Unfortunately it has a very noticeable lack of torque. As soon as I touched the blade to the spinning disk it started slowing down. This was with almost no pressure. Tried going in slowly, but even just grazing the disk starts slowing it down. Tried a worn serrated kitchen knife and it stopped completely. Again, using no pressure but the weight of the knife. It's an ok sharpener, but doesn't work as it should.

One of the grinding wheels is not properly positioned and consequently it doesn’t make the desired contact with the blade. As a result I find myself adjusting the position and forcing the knife within the slot so that the blade is sharpened. Otherwise the sharpener works well for the price.

Sharpened two kitchen knives today and it was a breeze. I should have upgraded to an electric one years ago, I'm glad I finally did. It is really easy to use and I like the fact that it has coarse and fine slits and what's more is that it guides the knife to the perfect angle. Highly recommended

Quickly sharpened my knives. Easy to use and for anyone who has issue with their hands like, holding things, this is much easier so you only have to hold the knife in place. Very convenient and efficient.

Cheaply made, dies under light pressure

looks nice and sturdy. Serves it's purpose

Not very good at all....hard to get in at correct angle
