I’ve watched the flame a long time, and I know how the tempering cycle plays out. A heat‑map algorithm could shave a few minutes off, but it must be grounded in the real temperatures the forge gives us. If the math lines up with the feel of the steel, then it’s a tool I’ll accept. If it just promises speed, I’ll need to test it on a full batch before I trust it to make the blade.

You’re right, a blade that looks good on paper but feels like a lab notebook isn’t worth the effort. I’ll gather actual flux data from the forge and the quench tank, then run the algorithm through a handful of test pieces. If the results match the heat we feel, we’ll have a blade that looks sharp and feels right.

I’ll lock in a high‑frequency probe so the quench spike is captured in real time. With those precise readings, the algorithm can adjust the temper curve for every blade, ensuring the edge is both mathematically sharp and true to touch.
