The Rocky Mountain Switchblade features an aluminum ferrule with an almost 3" total cutting diameter from the 2" over-the-top expandable blades and a 7/8" cut-on-contact tip blade that starts working the instant it makes contact. The Switchblade'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 Switchblade slices through hide and soft tissue on contact and makes a devastating wound channel.
