Hi Robert: Obviously you're phishing for answers to steer your own work. Not a bad thing. :thumbup:
Though I'm not in this market much, I'll add in aspects which don't care how much the maker charges for a handmade knife.
My website phrase has always been: 'No one NEEDS a custom knife--they have to want it.'
Pardon my rephrasing your question: Here are things which most people DO want. They don't want them to be neglected.
Long term value: Is this maker pacing themselves for the long run?
Presence: Is this maker's work currently noted or are they disconnected and obscure?
Brand identification: What is different and unique about the work which identifies it among others of equal quality/pricing?
Aftermarket values: if the buyer decides to sell an unused knife. If they can't sell it for close to original cost OR there is no history = pricing is simply wrong, no matter how much time and cost it took to build.
Character: The elephant in the living room. The maker simply has to be a standout in communication, business ethics, and timeliness. Miss any one of them and detract points.
There are more, but this is a short list.
Good thread!
Jim
