More Hardness Discussion

[Bud]

This is getting good! I've simply never thought of this particle size thing in relationship to the thickness of the edge. I've also never considered how hard these carbides are to the things we're trying to grind them down with. I know this much from personal experience. You better be using an abrasive that is a lot harder than the thing you're trying to grind down unless you've you've got a lot of time and nothing else to do. That picture of a boulder sitting on top of a pedestal makes an impression. Raises all sorts of questions for me.
