Hardness should be ~61hrc. The steel seems to be 1075 or similar.

The tangs are not straight and do not have a uniform taper. The blade also has a forged distal taper which makes a little more difficult to mark the center line. To mark the center line, I use a carbide tipped caliper.

Good luck, these are a lot of work and a lot of fun.

i've got 5 of these and plan to do the same process
thanks for the HT guidance here
although I don't have a sub zero quench
