I haven't met him. People appear to speak Hungarian to him in greeting(or me). When I was at uni, a guy in the marching band(not named Farkas) was also a doppelganger for me, to such an extent that I was always being asked why I wasn't at band practice. (because I can't carry a tune in a tin bucket).

Heat treat time! The magic that turns (relatively) soft carbon steel into a hardened blade. Something to do with the carbon being transformed into Martensite.

You heat it until it glows orange/red and then test it with a magnet. If it doesn't stick (it did when cold) it has reached critical temperature. Heat a little longer and then quench in oil.
