It's a deburring tool.

The other will stone out at 7/16 wide with edges about 7 3/4" long. Paid $7 for it.

Went back and found a new one. Will be 1/2" wide with 6 3/8" edges. All three sides fullered. Looks even meaner with dull grey fullers and shiny blade. Under $4. Maybe the next one I find -- dull the point and edges and make a training knife, or even a ( gasp ) burnisher.

 
Rusty it sounds like you've got a new hobby reincarnating old files. It's like "arts & crafts" meets "self-defense", I like it.

Yeah, I have a machinist's scraper made from an old triangular file and I find it very useful -- I almost mentioned it in the other thread, but I thought you wanted a stiletto. (I wonder if that new Fairbairn-Sykes of yours has anything to do with that decision....)

If you're going to use it for deburring please disregard that suggestion for tempering I posted -- you want it full hard for that. But you could still give it a giraffe bone handle!

I didn't post here a few hours ago cause I been off trying to find out where you hang out.

Anyway, so files are O1 and+/- rc 65. You suggested a 425 oven to temper. Please don't get mad, but I know just enough terminology to really confuse myself. I thought that it had been tempered at rc65. What would happer in the oven would be called drawing or maybe normalizing ( not annealing ) and wouldn't need a quench, just slow cooling. But the process would take the rc down to what? 57/59?

Elicidate, please if you would.
