C83 Persian

C95 Manix

C159 Air





How it feels in hand though is very unique among Spydercos. Even among manix iterations.
A C95 spirt run would be pretty cool, curwear, m4, etc.
Not without customization, but I'm sure it could be done. Honestly, for a redo, they could mill in a wire clip fitment without changing the footprint of the knife. Never out of the question, but ultimately in Spyderco's decision court.
