Thanks, all, for the comments. I don't yet have my replaced knives as my mail situation is complicated, but I am looking forward to getting them.
The clip on my Spyderco Dragonfly (the FRN model, a plastic clip integral with the scale) broke off while it was in my pants pocket clipped to the edge of my pocket. I was lifting and bending and moving things and I never found the broken clip, just found the knife in the bottom of my pocket with a jagged stub. This was unusual behavior for me, as my work days are suit and tie, so the knife was only lightly used.
Unfortunately, there don't seem to be any alternative Spyderco models in the same price range or less as I prefer a traditional lockback and not a liner lock. I realize the Ladybug is small, but I am hoping that the serrated edge will nonetheless be handy. I'll likely put a Bug on my keychain as my work knife (even the Dragonfly got some surprised looks from coworkers) and drop the Ladybug in my pocket on weekends.
Cheers,
Matthew
