The Rocky Mountain WarheadX features an aluminum ferrule with a 1.75-inch cutting diameter and a cut-on-contact tip blade design that starts working the instant it makes contact. The Warhead’s jackknife blade-deployment system will not open until the blades have made full contact with the animal, making broadside and even angled shots more deadly. With its aluminum ferrule and durable 0.035-inch-thick stainless steel blades, the new Rocky Mountain WarheadX slices through hide and soft tissue on contact, yet it has the strength and sharpness to bust through bone.
