I have been mulling this over, agreeing with a lot of what others have said, but I have to say that in the end, my philosophy is that I want to make knives that please myself and please my customers, whether they are looking for performance, feel, fit and finish, particular design elements, etc.
Most of what I make these days are modern style field/utility knives, but I also make reproductions and re-creations of historical pieces occasionally, and both my intent and the customer's expectations may be very different between the 2, so I'm not sure the same philosophy even applies, although I do believe it should be the goal of any craftsman to bring the best of their workmanship to every piece they make.
