Hello from Asheville, NC! I just finished my first brake drum forge. I am very intrested in smithing and would like to try my hand at knife making. I have a few questions though. What does HT, RC, and HRc stand for? Also Would I be better off using coke or coal? Lastly I have been told a good thing to try my first kinfe out of is a non case hardened file. How do I tell if they have been case hardened or not? Any input on these subjects is appreciated!
A few pics of the brake drum forge I just built! Completed it for just under $40,
