Cast Iron Knife
I'm pretty sure I just made a knife from cast iron.
I aquired an old Fairbanks Morse & Co double open-end wrench--most likely a 1920s vintage. I hammered it out, ground it, heat treated it, finish ground it, and etched it. It felt like I was working tool steel the whole time, but the etched finish looks different than I expected. It hardened fine--easily passing the file test. I know they made cast iron wrenches a century ago, so I'm fairly convinced that's what I have here. I just made a brittle knife, didn't I? __________________ Andy Garrett https://www.facebook.com/GarrettKnives?ref=hl Charter Member - Kansas Custom Knifemaker's Association www.kansasknives.org "Drawing your knife from its sheath and using it in the presence of others should be an event complete with oos, ahhs, and questions."
