Kota Diamond Rod is an Aggressive Knife Sharpener
By CS on Reviewed in the United States on June 5, 2025
I’m an experienced knife sharpener having done it for 50 years. Over the years there has been many designs for knife sharpeners, most not very good. Fortunately the Kota Diamond “stick” sharpener is quite good, but you should understand what it is and what it is not. The Kota sharpener is appropriate for when you want to do a major reconditioning of a knife blade. A knife that has been abused and has no sharp edge at all. The Kota is impregnated with diamond chips that remove lots of metal fast. It is not a “touch up” sharpener that you use on an already sharp knife where you want to keep that sharp edge at its best. For that purpose you want a fine grain ceramic sharpening stick. Green Elephant is excellent for that purpose. C.S.

Meh, probably will return it.

Use it like a steel and it works, use it like a sharpening stone and it will fail quickly. It will straighten the burred or rolled over edge of a knife fresh off the oil stone, anything more than that and will have a very life. I could see and feel the diamond surface go completely smooth after a small amount of very light use.
