Yeah, I used O1 tool steel for the blade and hardened and tempered in my little toaster oven (not the most accurate HT oven, I know, I but all I could find after the move). One thing I liked doing with knives but never thought to do with razors was marquenching, it made a really nice, durable blade and I wonder if it might work for a straight razor too. The bainite in the steel made the knives almost indestructably flexible and it seems just like what the thin edge of a straight could use.
Go ahead, give me your best shot!!! :D I've learned so much from this forum from when I first picked up my great grandpa's old straight razor to making my first hacksaw blade kamisori (bad memories there, face looked like a tomato after :eek: ) and everything I've learned this past year before I joined was thanks to the amazing people here at SRP, funny, kind, sharing, and not afraid to say what needs to be said.
