hardening and freezing | with dry ice, heat treatment, cryo, stainless steel, knife making

In this episode, you'll see how I optimize my process of hardening multiple blades. To harden high alloy steels, a dry ice treatment is recommended. I also use the dry ice to keep cooling my Quench Plates (see • Aluminium Quench Plate... ) after each blade.
Please also check out this road movie where I try to explain the hardening process: • mal eben... Trockeneis...
I would be very happy about your feedback in form of a comment!
