I'm hooked on the SpyderCo Stretch, I have had 3 total now, lost 2 to the uniform company at work by forgetting to get them out of my pants pocket. I've lost a regular one and a ZDP-189, they don't allow pocket knives at work now so I have been able to keep this one! I did bend all 3 pocket clips, and the pocket clips all broke after bending them back, so my current one has a custom Kershaw pocket clip that has held up better for over 2 years now! I also found the ZDP to be hard to sharpen, but I love SpyderCo.
