Al Mar AMK2209 3" Combo S.E.R.E. 2020 OD Green. The Mini SERE 2020 is world renown as one of the strongest tactical folders in existence. Originally designed by Al Mar and Colonel Nick Rowe in the early 1980’s for the U.S. Army's SERE school, today's updated models are stronger and lighter - the most precisely crafted versions we've ever made. The Mini SERE 2020 features 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.
