Floats the hard way

Re: Float Question ()

Wow, that's a hard way (literally) to make floats.

Tempering a file to blue-gray would probably take its hardness to about Rc50 or about 475 Brinell. That's a good/typical hardness at which to *use* a float, and soft enough for sharpening, but not so good for *making* one.

Annealed O1 is about 200 on the Brinell scale, or ~Rc13. If I were going to make my own float then I think I would work from annealed stock and heat-treat it. Better still, I'd pay somebody with a milling machine to do it...
