Unpopular opinion: my coal forge beats my gas forge for knife blanks, and 6 months of tracking proved it
I switched from coal to a little two burner gas forge last spring because everyone said it was cleaner and faster, and for the first 3 months I was sold on it. Then I started logging my times on the same 1084 blanks and the coal forge was beating it by about 10 minutes per knife because I could never get the gas forge to soak heat into the thick spine without roasting the tip. Now I run coal for the rough shaping and only fire up the gas for the final normalizing passes, which honestly was not the plan at all. So which one actually wins in your shop, or am I just bad at tuning a burner?

roasting the tip" is the whole problem with gas on thick stock, you nailed it. Coal lets you heat the spine slow without cooking the edge, gas just blasts everything at once. I run coal for the heavy stuff too, so you're not crazy.
