More interesting opinions I must admit, thanks for pointing them out.
As to what was stated about the oven doing the work this is wrong, the oven is just a heat source, like a gas or coal forge, torch, or a good wood fire.
The knowledge learned as to how to apply the heat, to obtain the most from the steel is what heat treating is about, but then again thats just part of the process, the right quench oils , soak times, normalizing cycles, pinning down the right tempertures , then tempering heats and cycles these are all part of the heat treating process, thats what heat treating is about, not just popping it in an oven for a certain amount of time and then taking it out. This process is all done by the maker by hand. Sure an oven comes in handy because it comes up to and maintains a certain heat but thats just a heat source, without proper knowledge and dedication its worthless..
William, I agree a piece of steel doesn't need to be heat treated to cut, but to perform to its full potential it does, unless your looking for a pry bar, BUT then it even needs to be heat treated so it gives and doesn't break with out bending like a noodle. I have great respect for knappers that is an art for sure, but even the indians threw away their stone knives when they discovered steel, and just because they didn't have the knowledge to get the most out of it back then, does that mean we should settle for the same today when we know how to make it better. Blacksmiths knew the benefits of heat treating steel, they knew how to harden plow points, knives and axes. Just because it wasn't heat treated years ago, doesn't mean it shouldn't have been, it just meant they didn't know how or they didn't have steel capable of benefiting from heat treating.
Thanks everyone for participating, you have all opened my eyes to the different definitions of the word "knifemaker".
