S7

[Cooper's Forge]

S7 knife. one of my dies on the Scotchman Ironworker broke so I called the manufacture to find out the alloy. The guy tells me it's S7. I have never forged it before so I did some research. Air hardens and tempers at 1200 degrees that's really hot! After the tempering process I oil quenched in clean 10W40? The blade turned some crazy colors ! Pinks, electric green in areas golds the blues. All very weird
