The Injection 3.5 folder is a Todd Rexford design with milled G-10 scales and a stout liner lock frame. It features custom details that include a decorative pivot, machined countersunk thumb stud and a chamfered backspacer too. The flat ground drop point blade has a bead blast finish and plain cutting edge. The Injection is loaded with all the things you'd want in an everyday carry knife, including a reversible tip-up carry pocket clip.
The Injection 3.5 is the larger version of the Injection model, and has the same custom features as the regular version.
