Hello everyone, I'm new to this site, but everyone here seems to give rather in depth answers to other peoples questions, so I figured I would ask one of my own. I just changed the rotors on my vehicle, they seem to be a cast iron of sorts. I was wondering if it is possible to turn them into a knife, or blade of some kind. If I need to build a hot fire and hammer away for days on end, I'm willing to. But I would like any and all pointers. If possible will you try to keep your answers in laymans terms? I am not quite as fluent in the metallurgy lingo as I should be. Thank you for any and all help!
