Sure it is. Regardless how the experts tell you it isn't (for knives) it's easy to make springs from 1095. No special equipment is necessary, except some fire bricks or a charcoal or ceramic heating surface, a propane torch, and some canola oil.
Now, before the experts tell us that 1095 requires precise heat treatment for maximum efficiency- it doesn't for pocket knife springs. I have made thousands of them. 4 broke-all from the same piece of steel. Most of these springs are leaf kick springs for automatic knives, so they get a little more flex than slipjoint backsprings.
I have explained my very non-scientific procedure before, but if anyone is interested I can do so again.
