A knife is worth what a customer can sell it for on the secondary market.

While this may be true (I don't agree with the statement) it offers no advice on knives the customer do not want to part ways with.
You can price a knife whatever you want, but the value is settled and cemented by the customer when he/she purchases it.
You cannot define value, you set the price, its the customer who defines the value with his wallet by purchasing your knife.
BUT for the average Joe. Selling a kitchen paring knife for more than 40 dollars when a customer can buy a 60 piece knife set from Wally World for the same price is a hard sell for most knife makers,
You won't be able to sell more expensive knives while you're on that mindset, I mean the "average Joe can't" but also in the mindset of looking what other knifemakers do.
You have the develop your customers networks, tell a multiple year/decade consistent story about your knives and your principles and not compare yourself everyday with other knifemakers since every person is different and the only coincidence is the knifemaking.
Also, knifemaking is only a part of your success making knives, it reads like a oxymoron, but is not, you need to be good at selling, good at promoting, good at negotiating, good at closing a sale and good at promoting the next one. These are additional skills most of the knifemakers I know neglect, not all, most.
[edit]
Forgot to add how I price my knives.

I have a base price (I know I cant post $ but its $250 its for explaining sake

) then carbon damascus is x times that, stainless damascus 2x carbon damascus, then I have fixed plus prices for stabilized wood (+$xx) bolsters (+$xx) mosaic pins (+$xx) hand tooled sheath (+$xx) etc etc
And then I have one offs prices for rarer steels or complicated custom orders.
This system helps me quote a knife very fast and on the spot while a customer asks me how much it will cost.
