The Rajah folders, designed by Andrew Demko, are big enough to approximate the feel and heft a fixed blade Kukri. Their broad, downward curved blades exhibit the best of a Kukri’s characteristics. First, their unique shape presents their thin, hollow ground edges at just the right angle so they naturally bite deep instead of bouncing or skidding off. And secondly their points are thick, wide and sharp enough to pierce even the toughest targets. New Tri-Ad lock.
