Trakker / Ocelot
Spyderco Wegner Trakker Prototype      

Blade is BG-42, and is unmarked except for the steel desigantion and Tim Wegner's mark, with grooves cut in both the thumb ramp and choil.   Although the clip mount and contouring of the FRN make it difficult to see, the pivot is adjustable.

Handles are green FRN, contoured in a manner similar to the Native III.  The "tracks" appear to be molded into it, rather than cut, as they are on the G10 "Ocelot" versions of this design.

Construction is dual liners and open frame with steel spacers and lanyard tube.  The stop pin for the nested compression lock serves dual duty as one of the spacers.   Handles and liners are both drilled and tapped to allow tip down clip mounting for either right or left hand carry.
