It's funny how hobbies can be so different from each other. A lot of musicians will pay top-dollar for vintage instruments, regardless of their cosmetic condition. A well worn guitar shows that it served someone well for a very long time.
I don't think anyone will pay top-dollar for a well used vintage/rare Sebenza. People want everything new-in-box in the knife world.
This 64' Strat is going for nearly $20,000but that's really common in the music world. If I had 20 grand, I'd play the hell out of this thing.
I'd pay a pretty penny for an H Sebenza. User or not.
