The SERE 2020 3.6” Blade is world-renowned as one of the strongest tactical folders in existence. Originally designed by Al Mar and Colonel Nick Rowe in the early 1980s for the U.S. Army’s SERE school, today’s updated models are stronger and the most precisely crafted versions we've ever made. The SERE 2020 features black G-10 handle scales, pillar construction, flow-through design, and our left/right reversible Deep Carry Pocket Clip that provides discrete carry and delivers the kind of performance you need in the real world.
