Yeah I usually anneal the whole mower blade then cut the knife blank out, Grind do my filework. Then I would Heat treat it and temper.
Thanks for the comments guys. After making these I realize I am NO knife maker. It was fun while it lasted but it got old REAL quick. A knife maker surely has to have a passion for the work, there is alot of work to making a knife. Too much detail sanding and such for my lack of patience. LOL
