Wonder what is to become of the Wrex since Leatherman now owns PocketToolX?
Seen those new one piece tools; Cam, Pump, & Rail - 'cept they are geared around weapon users. Why not redesign the Wrex with that as the main implement with perhaps the opened & closed end from the Piranha, or either of the two designs? Am sure the oxygen wrench would go in there. Add a lighter weight Bit Extender, and a #8 & #10 Torx double-ended, and whatever for the handle grip thing. Of course the carabiner on the end.
Just a thought.
