Hi, i am having trouble hardening my knive, and i am not sure what went wrong. i use 1084, a small propane forge and canola oil. i know this is not the optimal setup, but it worked on one of two knives i heat treated (the first one). what i do is i get the blade to a glowy red color, almost orange, then i quench it verticaly without hesitation in my "quench tank" wich is basically cans of beer tied with duct tape into a tall cylinder. i pre-heat my oil to about 120F. the last knife i tried to heat treat just wont harden! i tried twice and i wonder what could have gone wrong and what can i do to harden it properly without sending it to a professional service or buying a kiln since i am kind of very low on budget (i am a student).
