More about the product and its functionality:

There are 2 slots on the tool for the sharpening job – a left side and a right side. User need to sharpen the knife in both the slots. Try to pull the knife in the same direction and keep it away from the tool.

After the purchase, I wondered how long the belt will last. But that depends upon how many knives you sharpen. I was able to sharpen 14 so far using the medium belt and I got about 10 strokes each side, then went to the fine for 10 strokes each side. I finished with about 10 strokes per side with the super fine belt that it has. Remember, you don’t need the medium or the fine belt if your knife is already sharp.

It runs on 1.5 amps and features five belts that are included but grits are not labeled. The coarsest is finer than the 60 grit and indeed will be rarely needed.


Overall, it is a superb tool to bring sharpness to all the blades that you may have at your home.
