OK, I have been kind of playing around. This is both modern and period. I made a striker for my modernFiresteel(ferrocerium rod) heat the metal(1095) and beat it, then quenched it. It is now hard. Wroks great with the Firesteel.
A) will it be too brittle?
B) will I need to temper it to get it to work with flint?
With the steel im shaving off bits of it. BUT with flint and striker, the flint will have to shave off bits of the striker? Correct?
