Another rather large heat treating study! This one took quite a bit of time, effort, and money. If you want to support further research visit Patreon.com/KnifeSteelNerds and become a Patreon supporter. All of the money I receive that way goes to knife steel research. And you get some perks like seeing articles and videos early, and at a high enough tier you get a free Knife Steel Nerds mug!
