Doesn't sharpen as good as I would have expected. Ten passes and my knives are marginally sharp. I guess after many more passes, I'd eventually get what I expect...a keenly sharpened blade. (in my opinion)
I've only had this for a day and sharpened all my knives from carbon to stainless steel. Using this with the diamond sharpening steel I also purchased from makes a very good combination.
My fiance loves his sharpener...says it works really well!
