Which stones would you recommend, and which grit? It seems 3 stones are needed generally.
I use two stones for 95% of my sharpening. DMT Dia-Sharp 6X2in. in coarse and fine. I glued them on a peice of wood cut to fit the stone to make a cheap small bench stone. $19.99 for each at Smokey Mtn Knifeworks. Right now they're shipping for free too. I really take pride that my knives are super sharp. They might not be able to whittle hair but they have a good working edge so I really don't think you need to spend hundreds on stones or sharpening devices. Give hand sharpening a try. You learned the art of sharpening a chain saw, no different with knives I think.
