Hi all,
over the last few months i have managed to get hold of a few old sheffield steel files.I hope to have a go at turning them into knifes at some point.Now i understand that they need to be softned first.I understand that part.Then rehardened.I understand that part.Then tempered.This is the part i am not shure about.I will be using my domestic oven to do this,and an oven thermometer.Do i,
1 heat up and quench again
2 heat up and let it cool slowly in the oven
3 heat up and air cool.
Thanks in advance.
regards Chris.
