Thread: A question on Letter/Number puches suitable for hardened steel

Yes a stamp would certainly work on the handles QC, but there's not much danger of me painting these:





Interestingly, one of the top French guys doesn't like to use them with handles because he likes to get the vibrational feeback from the wood as he is rasping.

I do in fact have a dud that was coated. We got a few files coated, just for the hell of it, to see what gives. Total waste, and rendered brand new files completely and utterly useless! They just skate over the top of the metal. So what I'll do as a test (when the Dremel is fixed, and crowie has given me a clue on that) is to have a go at the dud Milled File shoulder (this is the file that I referred to earlier about wearing out 2.5 files trying to sharpen it - it's still not much cop as a float because of the coating). None of us really understand why the coating has very little dulling effect on a point (essentially of no dimensions), but on a one dimensional edge it completely dulls it, or prevents it from cutting. But that's the reality, and the coating ain't for files.


You may recall that you and I had some private discussion about my crackpot theory on the coating keeping the rasp point in tact until the coating wears away on the point exposing a still brand new sharp point (my theory being that the rasps may actually wear in). Of course you debunked this , saying that it would be more likely that when the coating molecules came away then it would probably also be with particles of the steel tooth as well. Tell you what though, it sounded good to me!

OK I'll start breathing.
