I got to play with my new KO Work Sharp yesterday. I've never had the patients nor the ability, for whatever reason, to sharpen knives very well but the Work Sharp makes it pretty dang easy to get knives incredibly sharp.
Like I said, I'm not very good at sharpening knives so we have a couple ceramic knives in the wife's kitchen and those things are razor freakin sharp so I used those ceramics as my comparison for the two knives I sharpened with my new KO Work Sharp. Since this thing is brand new to me I just followed the sharpening instructions in the users manual and I would say the two knives I sharpened came out as sharp as my ceramic knives, which are VERY sharp. It'll be interesting to see how long they hold their edge. I don't expect them to stay sharp as long as my ceramics but at least I know I can get my steel bladed knives just as sharp.
