alright, here we go. Another dumb question from a new guy. I've searched as best I could for the answer, but the results are saturated with Tig welding razor blades or Damascus straight razors.
Is it worth a try to forge weld all of these used utility knife blades to make a billet? Soak them in acetone, tie them with wire, heat them up and beat them till stuck.
I don't really want to buy known steel. I like making things out of trash. Are the blades too thin? Are they even carbon steel? Any opinions?
