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 Rocky Mountain Switchblade slices through hide and soft tissue on contact and makes a devastating wound channel.
