Hi Friends,
Wow, there's a fair amount of some pretty erudite stuff writ up here! Guess, I'll add my two cents to the pile.
If one needs to make at least 100 (or perhaps over 500) blades to get a firm grasp of the mechanics and techniques of bladesmithing, then you got to do something with those buggas! Sure, give them away to family and friends; trade them with vendors and merchants...but, hey, what the heck, why not sell them to honest folks for an honest buck too?
I'm just working at getting to the starting line with bladesmithing, but have some experience along similar lines with jewelry making. The pinnacle of my jewelry making career was in the late eighties goldsmithing in Beverly Hills. You can bet the cost of my work then (time and materials and customer price) was considerably different than that of the bone and antler carved pieces I started making in the mid seventies. Never-the-less, all along the way, no matter what level of skill or value of materials...I sold my wares! Sure, I paid my dues, over and over. But to me it was always, "hey some one just gave me cash money for my handwork, heehaa!"
I also developed in three different ways. I designed "lines" of jewelry and hand made dozens, hundreds and thousands of them. Thus I got pretty darn good at any given step of putting them together. They sold for pretty low prices ($10-$100) and sold well. I also did a lot of repair work. That provided liberal amounts of customer satisfaction, learned me a lot and made fair wages. Then there were the one of a kind pieces, whether for shows or galleries or custom orders. They were lots of fun, could tie up fair amounts of capital in the way of materials, might take a while to get completed and/or sell, but usually returned a good net earning.
You sure do have to wear lots of hats to be successful in business: tradesman, manager, salesman, designer, visionary. Most any business of our ilk starts out with the tradesman. For instance, someone good at cooking or baking soon finds out they need to be good at a whole lot more too to make money at cooking and baking. Never-the-less, for me, it has always been the love of my craft that has sustained my drive to develop other capacities too. Maybe its the same for others?
When it comes to pricing, all the equations and suggestions above are good. It really does come down to you though, and how well you can look someone in the eye while holding your wares and neither under or over value your work. This can be a damn near therapeutic place of self reflection and self integrity and self growth. It is sometimes a painful place to be in, and one of the most difficult in the whole journey. I appreciate the question, always have, probably always will.
Good luck grappling with it!
All the best, Phil
