Matt, that sounds like a bit of a brown trouser moment... :eek: I don't currently have a tool rest. I have plans to build one soon, but not for grinding my bevels (more for profiling, fittings, etc.). I do bevels all freehand. I suppose it may not be the easiest way to do things and there's a bit of a learning curve, but I'm glad I learned to do it that way.
A maker I know uses a very small rest. He doesn't rest the blade's spine on it, but uses it for his finger to ride on. His finger supports the blade and he still has the ability to feel what he's doing while having the rest to keep his hand a bit more steady. If I was going to use a rest, I think it'd be in the manner he does things. But you're right-thin blades make for scary moments when getting sucked in between the proverbial rock and hard place. Especially when the hard place is humming along and 60 grit. :D
