Just reccommending this product, as it is idiotproof. I don't really like the feel of using it, but it puts razor edges on my knives in no time.

I just put a nice shaving edge on my RD4 in like two minutes. It did the RAT3 D2 in about 1 minute and made it as sharp as any knife I've ever owned.

Again, I really like the feel of sitting down with a stone, and screwing up my edge because I suck at sharpening. Obviously, the results aren't as good. Sooooo... If you're sharpening impaired as I am, check out the Spyderco Sharpmaker!
