Nathen,
Unfortunately I do not have much time to get involved in the forums. However, more knifemakers should be asking the questions you are asking. I have been making knives for 25 years now, that has given me some time to ponder the same questions you are asking. My opinions (and they are ONLY my opinions) are this:
The main factors creating demand in the market place are quality of craftsmanship and design as well scarcity. This applies to using knives as well as the so called "art knives". I once was lucky enough to overhear a very advanced collector explaining to a new collector his philosophy of collecting. In essence he told him to look for a maker (new or established) who takes pride in immaculate workmanship. This has to be in conjunction with a good sense of design. If the maker continues to develop new designs and ideas and you can pick out his pieces without looking at the mark, you have found a winner.
As in any of the arts, developing a style without repeating the same work will set the maker apart from the rest. Of course all this means that the maker can only produce a limited number of pieces. For a new maker (I know this from experience) that means selling very time consuming pieces for a disproportionally low price for several years. However this should be looked at as a reasonable price to pay for eventual success.
If the work is truly outstandng, it will not be long before collectors start paying attention, especially if the prices are reasonable. As with all things that are rare and beautiful, most collectors of a specific type of knife will want at least one example inhis collection. With increased demand come the higher prices. For makers who love what they are doing, higher prices will provide the incentive to produce more elaborate and time consuming pieces at a reasonable wage.
Never forget to treat your customers with respect, and never forget those who supported you when you were struggeling to make a go of it.
