That thing is a beast!I appreciate unmolested tools but I feel this one deserves the user abuse damage that would affect hanging and performance to be attended to. It looks like it was beaten off a handle at some point, smashing the collar mouth in on itself enough to make up to a .25” sharp lip on the top.
As it arrived:
Material removed and relieved to not cut into a new handle:
The back edge looks like it was a casualty of the same maneuver:
Still needs some careful flat filing to finish that rear of the bit.
Honestly: How people treat there tools sometimes gets me mad! Or was this transport damage?
It has to be hardened for a reason? Why else go to all the trouble of hardening the blade and the poll?
Well,Kevin,this is Very speculative,what we so often have to do here,and it's very easy to be led astray by conjectural thinking,so keeping that in mind:So you are saying that they used to harden a poll to attach something on it that is not hardened? And if so, how????
And lets not forget: Hardenable steel wasn't a commodity like it is now?
Shear steel was one of the early processes to obtain a more/less homogenious hcs.Iron strap segments were carburised,with C-content further re-distributed by means of repeated welding and faggoting.talking about metal to make sheers out of?
Small knives are never made out of multiple steels. That wouldn't be economically feasable. Unless we are talking about bigger knives of course?
