.Al Mar's SERE 2000 is one of the strongest tactical folders around and delivers the kind of performance you need in the real world. Originally designed by Al Mar and Colonel Nick Rowe in the early 1980s for the U.S. Armys SERE school, todays updated models are stronger, lighter and the most precise versions Al Mar has ever made.
