These inexpensive, basic sharpeners have a tungsten-carbide abrasive set into a plastic handgrip. To use, hold the knife steady on a work surface with the blade facing up and, holding the sharpener in your other hand, run it along the length of the blade. Easy.

Pros:The sharpening angle is set so you don’t have to worry about it when you sharpen; very quick; very simple; very cheap; pretty effective.
Cons:Feels dangerous to some; doesn’t create a polished edge.

Is it right for you?

If you’re looking for a super-simple, super-quick sharpening option, and you don’t mind the finish being a bit rough, this could be the ticket. You can’t beat the price.
