Thread: Re-hardening a vintage razor?

I have never heard of a blade losing its temper from anything other than overheating. Could you post more details and/or photos?

Dylan is dead on. Only thought other than heat is if it's surface hardened and you have worn through the hard steel exposing a softer core.

If it's a wedge to a quarter hollow, maybe on a new HT. You will have to keep in mind it's a mystery steel, that you will loose about an eighth of an inch in length, and the blade will still need cleaned up. Most who heat treat would pass on such a venture & honestly most blades aren't worth the money and effort. If it's a half hollow to full hollow...forget about it as it will most likely potato chip or crack at the quench.
