Tac-Force Black and Gray Spring Assisted Tactical Rescue Knife w Integrated Seat Belt Cutter 3.75"

Tac-Force 3CR13 Stainless Steel Spring Assisted Tactical Black and Gray Tactical Rescue Knife with Integrated Seat Belt Cutter and Glass Breaker The spring assisted knife is quite a remarkable blade. Developed because of laws and municipalities that bar or prevent one from legally owning and/or carrying automatic switchblade knives, it is the perfect solution! This spring assisted knife, in contrast to a standard automatic switchblade knife, is not opened by pressing an activating button (the button is what gets an automatic knife classified as illegal) , it is opened by using the index-open "flipper", which creates a hand guard when it is open. The beauty of this spring assisted feat of engineering lies in its pivot area where a wound-up internal spring has been nested that assists in the opening of the knife. It is this spring that differentiates this spring assisted knife from its automatic switchblade / OTF cousins as well as the standard folding, manually-opened, lock blade knife.
