There are stones on the market for these horizontal wheels, don't remember where I saw them but they weren't too expensive.Wow, while viewing for the 2nd time, and checking out the opening shot of the horizontal grinding/sharpening wheel, I realized I could take an old potter's wheel and set it up to do the same thing. It has a rheostat, enabling a wide speed selection, and it would be very simple to set up some type of grinding stone with a water drip, or just adhesive abrasives. Made my day!
I love them as well, but I LOVE rough and rustic in most my obsessions lol I would have a full set if $$ where not an issue, and I'd be using them all the timeI like and appreciate his knives for what they are - rough, rustic, and somewhat delicate. I'm drawn to them even though I don't think that they're very well suited for most uses, I don't think that they suit a pro kitchen role very well at all.
