Buy ZWILLING Sharpening stone

The stone has a nice weight to it and doesn't slide around on the counter while I'm working. Took my chef's knife from frustrating to razor sharp in about ten minutes.

I've been sharpening my paring knives on this for a couple weeks now and the edge it puts on is noticeably finer than the old stone I used. It feels dense and heavy in the hand, and it hasn't worn down or dished out at all so far.

My chef's knife was tearing tomatoes instead of slicing them, and ten minutes on this stone brought the edge right back. The stone stays flat and doesn't dish out like my old one did.
