Newbie blacksmithing attempt at hardening my splitting wedge, which seemed a bit soft (the old Birch gave it a burr).

Filed that burr off, threw it into the sauna fire until red hot, then into an old pot of prehistoric tractor oil, flames and sizzling, etc.

Then back into the fire, guessing the temperature before remembering I have a thermal imaging phone in my pocket and back outside to cool down over night.

No idea if I did this right, but will find out :)
