Product Info for Buck Knives 591 Paradigm Shift Automatic Knife

Bucks newest automatic, the Paradigm Shift deploys in an instant when the Shift Mechanism bolster lock is deactivated. Simply slide the Cerakote coated bolster up and your knife is open! Denoted with gold fasteners, the Paradigm Shift is designed with premium S35VN steel and durable G10 handles to ensure edge retention, strength and durability. A Cerakote coated pocket clip allows for easy carry (where legal), and the bolster lock prevents accidental deployment. It closes the same way as opening- by sliding the bolster open to unlock the blade. Lock it closed by sliding the bolster back in place.image
