er that sword in the vid, the one that did my first-of-many 2 by 4 one-hitters is A8mod/TLS chipper steel
the one in the still photo is 8670m banite which I'm moving away from because of its fast quench requirements though it really is fine steel, will replace it with either S7, Diamondwear, or CPM3V, though I'm open to suggestions! I like 5160 too but it also needs a fast quench.
