Actually, think the first batch was more like RC 44, but still too soft if hammering hardened steel drill holders. Rc46/47 perhaps the sweet spot.

Duecey, This article hits home for me in a lot of ways. Starting Kahtoola (with you as an early advisor) included several similar sketches for the KTS crampons and even using some of the same vendors (Jorgensen, Phx heat treat). That was back in 1998 or so. Thanks for the inspiration and I hope to catch you in Flagstaff sometime! Danny Gio.
