Do you happen to know what kind of steel McKenzie favored for these hammers?
Thanks!

In Handout #3 on 3rd page there's mentioned " Graver: Mo-MAX Cobalt".
And thank you both.

Pretty sure it was oil hardening tool steel.

Yes, many of us used momax cobalt back in the day. It was probably the best material back then.
Vague recollection, not sure why or where; maybe McKenzie's videos... I seem to think I heard him say he preferred 1045 steel for chasing hammers. Relatively low carbon content allowed the steel to be heated red hot and then quenched, and it wouldn't require tempering. It was both tough enough and hard enough, without getting brittle. Sounded like it would make sense.

I made my hammers out of O-1. Excellent tool steel that anybody can work with.
