I am old school - still carrying the first Endura I bought. Remember the molded pocket clip model in FRN?
When that broke off at the Firehouse I sent to Spyderco for a couple of metal clips and screws, ground off the stub and screwed on the new clip. Worked so well I did the same to another old Endura to carry in the left pocket :)
Spyderco II. 8-10 years ago I bought one and lost it after about 2 months. Immediately bought a second, then found the first. They've been wonderful tools.
