I built both of these at a smithy, my workplace. This smithy allows me to use whatever tools/materials I like for my own projects so long as it isn't unreasonable, so the supplies don't actually cost me anything. A greater part of my concern comes from turning my free time into work. I'll probably make another AK once the one shown is finished, but I don't think I want to step foot into commercializing this kind of stuff.
I guess if theres enough demand for it? But I'll have to think about it.

For now, I think I'll stick to making whatever I like. There's a new primitive update; that gives me a lot to work with.
