Virtually eliminating bending and curling for confidence when hunting dangerous game. The blade is 406 stainless steel at 0.047" thick, and the ferrule on the 150, 175, and 200 grain models is made from A3 steel, which gives strength against even the toughest of animals. The 125 grain model features a 6061 grade all weather coated aluminum ferrule. Both the steel and aluminum ferrules are 11/32".
