All my mods are internal:
1) increase detente with a dremel where the comp lock sits when closed;
2) enlarge engagement portion of the comp lock (hammer, nail set and luck);
3) pivot assembly instead of lanyard tube (that had fallen out) - but got replacement tube from Spyderco, so that may change;
4) new torx screws throughout;
5) rounded square corner of tang that always bugged me (the corner that catches your pocket).
That's it. And then I beat the crap out of it!
