Heya folks, I am currently building a propane tank gas forge like the one in the picture below. I am also planning to increase my knive production rate to be able to make a little money with my stuff, but I do not yet want to invest several thousands of dollars into a heat treating oven. Now i was asking myself the following: Is it possible (and reasonable) to use my soon-built forge to harden several blades at once? Can I control the heat in there by sticking in a thermocouple sensor
