I am just getting into the knife thing, as far as compostion goes. I sharpen a lot of knives though. I think one of my sharpest is a 1095 CS custom, made by bradshaw. That thing is sharp! It is a convex grind.

I have also sharpened a few stainless that realy took a keen edge. Some of the factory ones that have take a really good edge are japanese made spydercos, and some of the benchmade knives. Knives of Alaska made from D2 are usually a treat to sharpen too...end up scary sharp. There are others too, I just don't remember them all.

I sharpen almost all of them on my Edge Pro, professional, except the convex. There have been a few that I have converted to convex using my buffer...no brands mentionable, just depends on how they are.
