Master smith told me to hammer hotter and I argued for an hour
Old timer named Gary at the shop in Tulsa kept saying my leaves were cracking because I was working the steel too cold. I told him I knew my heats, I'd been doing this for 4 years. Finally he just took the bar out of my hands, waited until it was almost orange-white, and did the same taper in two passes. No cracks. I spent a whole afternoon redoing everything at that temp and it worked. Still bugs me how stubborn I was. Anyone else get humbled by some 70 year old with a beat up anvil?
Damn, that hit close to home. The real kicker is that heat isn't just about making the steel easier to move. It changes the grain structure, makes it more forgiving when you hammer. Cold steel fights back on a microscopic level and you end up with stress fractures you can't see until they show up as cracks. Gary wasn't just showing you a trick, he was teaching you about metallurgy on a level most of us never think about. The stubborn part is hard to swallow but that lesson sticks with you way longer than if he'd just yelled at you.
