I'd welcome any posts about the grinders & process you are involved with (purely from a metal-head standpoint). Personally I need another hobby pursuit like a hole in the head but the knife making & heat treating thing is fascinating. When I travelled up to Reynolds museum couple months back they had some knife guys showing their wares. I selfishly swabbed each of them about heat treating ovens, quenching, salt bath... info for my engine parts one day. But you couldn't help but be struck by the aesthetics & uniqueness of knives.

Reason I was curious about grinding is I also spent a bunch of time online looking at home-made belt sanders typically used by the knife crowd. Some are rudimentary frames with wheelbarrow wheels. Others are friggen amazing: VFD drives, high end spindles & bearings, adaptable tooling & jiggery, sexy frames... I'd like to make a HD belt sander one day, not really for blades but just as a workhorse for profiling & finishing parts. Not sure if you are talking stone grinder-grinders or belted ones, but its all cool to me.
>These pieces are not 100% hardened yet and will have to figure that out later on. I have a guy who just invested $8800 on custom made fully automated grinders designed for profiling and sharpening the blades. I'll post a video if I ever get the chance.
