Making a knife out of a lawnmower mulching blade? Answered
I am planning to use a lawnmower mulching blade to make my first knife. I need to know how should I heat treat the blade. I have read about annealing, quenching and tempering but every source of information has different instructions. Since I am planning to do this outdoors, I thought about using motor oil for quenching. Would you please provide some ideas or suggestions? Thank you very much for all your help.
