    I’m interested in the A8 results. Were these done with low temper? I’m pretty sure busse uses a higher temper, somewhere around 900 degrees. I would like to see both results just for the heck of it. Also did you ever send a lower hardness ztuff sample to Larrin? I’m curious about a sample at 58-59 with low temper.

    I will be doing high temper a8mod, and samples with the ramp that’s recommended too. Z-tuff lower hardness sample is in the batch coming up with s7 and 1v. I have to order some more z-tuff, as I’m making another knife out of my remaining supply. :rolleyes: I have enough for one, maybe two samples left.

    Any news from the gentleman who is grinding Ultrafort and NZ3, Warren?

    A8mod, S7, 1V, NZ3, Ultrafort and 58/59hrc Ztuff are all contenders for the toughest steel good for knifemaking. Let the party begin!:D

    Larrin contacted him about a month ago, I think. Not done yet.

    Let’s hope he can arrange some time to grind those specimens, for the good of science.
