Materials+shop rate+(margin if not included in shop rate)=knife price
But hobby makers like me don't get anywhere near that, if we sell our knives.
Right now I'm making a giant bowie for a buddy, he wanted Damascus. That cost 220$, the guard is a piece of old wrought iron 10$, the handle material is Elk shed provided by customer 0$, the pommel is brass plate, 2$.
Shop time? Who knows! Consumables? No idea.
I work slow, I'm not that experienced so I make lots of mistakes and have to fix them. I've been working on the knife for about 6 months maybe?
I've already decided on a price that I'm going to charge, but I'm not going to make any money on it. My material cost will be covered, but the rest of the costs of producing the knife wouldn't really be covered. Certainly not my time.
All of that is to say, like
Lorien
and
ScarFoot
are saying pricing is complicated and the steel is one of the smaller considerations. Time, consumables and "special" materials count a lot more.
