OKC3S bayonet: a full-tang construction, 13.25″ piece of 1095 steel with a zinc-phosphate non-reflective finish, a stealthy sheath, and a “Dynaflex® handle ergonomically grooved to reduce hand fatigue.” Designed to be sharper, stronger, and more natural in the hand than its predecessors, the OKC3S is built to penetrate body armor and was part of the Marine Corps’s post-9/11 push to reemphasize hand-to-hand combat.

Army chose the M9 to match a different set of specifications. In particular, they wanted a good wire-cutter. The M9, the best wire cutter among several options, was also bigger and bulkier as a result.

You want a weapon,get the OKC,if you need a tool,get the M9..
