What hardening and tempering process did you guys use and what sharpening process did you use including stones and angles,i've only made one knife from an old file so far and i'm waiting for my forge materials to arrive so i can get my forge built and heat treat it,i worked for way too many years in the meat industry and have always sharpened my knifes at ten degrees with arkansas stones and always had a razor edge with a fair amount of durability but when i read about the testing you guys do makes me wonder how they would hold up,also one of my old workmates used to make knives for us out of files and he tempered them harder than commercial butchering knives and left the blade thickness the same from spine to edge which with the extra steel behind the edge and extra hardness made knives that were just unbelievable so i thought i would try make some knives along those lines but being a noob any information would really help
