More than half of the knives in my regular rotation are either discontinued, older sprint runs or customs (in 2 cases 1 of 1 rather than 1 of 1000). I enjoy carrying and using them … it’s the kick I get out of owning them. If I loose of break them that would be very unfortunate but it’s a chance I am happy to take.
If you get enough of a kick out of “pride of ownership” and the knife lives in a safe, that’s also good. Different people own / collect knives for different reasons … there is no “right” answer.
