Yeah, when the heat waves ripple through the steel, the grains align in these intricate, almost self‑similar patterns. It’s like the metal’s own little fractal dance. The key is to control the temperature swing and the cooling rate—slow, steady quench lets the grains settle into that beautiful pattern, but rush it and you’ll just get a chaotic, weak structure. I’ve seen the difference a slow heat pulse makes; it turns a rough block into a finely tuned blade. Keep an eye on the heat, and you’ll see the math of the forge right in the steel.
