normalized 3 times, quenched in Canola right at critical temp (lost magnetic so i think i did it right) and dont know if it did any good but the only tempering i did was to bury them in a bucket of sand after the quench and let them slow cool till ambient temp. And yes I have done a little of welding and woodworking in the past.
File skated right of of em and they took a good razor edge, hope they hold up. Time will tell.
Stabilized Box Elder on the first 2, Maple on the 3rd, and Water Buffalo Horn on the Fillet knife.
