I found myself getting more, and more interested in metalurgy, steels specifically. What the different alloying elements ment for the end user. In the case of knifes.
What different percentages ment for them. What different heat treatments do to rockwell. How different rockwell hardness numbers would act, with different blade geometries. Why do cryo or subzero treatments? How does all of this come together, and allow us to get a micron or less thick apex that lasts under use.
I just can't stop being fascinated by the different parts of what goes into these knives. One day, I got bored. I decided to turn an old saw blade into a knife. To see if I could heat treat that with some charcoal, a hair dryer, and some water. Then tried with another. I tried to see how hard I could get it, and how thin I could get it. While not failing.
That led to me buying some a2 (basically skd 12) trying to use that. Acquiring more and more tools. To (hopefully) do better work.
Now I've got cpm d2 I'm trying to make knives with, and cpm 10v arriving saturday. I didn't plan to start doing this stuff, it's like it just happened, and is continuing to happen. I couldn't be more excited about it though. Before I know it, I'll be sourcing hap72, and rex 121 (after I somehow afford a lot of tools necessary, if things keep continuing.
I always said to myself, "making knives would be cool to do one day, but I just don't have everything i need to do it."
I say all this like I've actually accomplished something significant. When in reality, I'm just doing something that I've always wanted to do, and just am realizing even if it doesn't lead anywhere. I'll have a good time doing it.
So anyway. Here's a knife. Its a2 steel...
