The Delta Dart is 8" long and 1/2" in diameter yet it weighs only 1/2 an ounce! Its comfortable handle is knurled for a positive grip and the butt is smooth and rounded, so its perfect for both thumb and palm reinforced positions. Like the CAT Tanto, the Delta Dart is made from Zytel¨. It is this super tough material that, when combined with the Darts sharp point and triangular cross section, accounts for its phenomenal piercing power and allowed it to be driven by hand right through a 1/2" thick piece of leather.
