ok, guestimation of steel? :3 I want to know so I can start saving up 
steels cheap, that's why it's becoming the new thing, machine fabrication is quick, forging it is more like blacksmithing with a torch and you can do so much with texture and patina...i like the pretty colors required to know when to anneal, quench and temper it.
I'll look into it and give some estimations.
