The Paradigm Shift automatic knife 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. 

Shift Mechanism™

Our patented Shift Mechanism™ serves as an advanced locking and safety mechanism. It not only locks the blade open when extended, but also prevents accidental opening when the blade is closed. 

G10

An almost indestructible resin laminate that is resistant to heat, cold, chemicals, impact, and other abuse. These tough, durable qualities make G10 well suited for a knife that will get well used in extreme environments. 

Made in the USA

At Buck, we are proud that this knife is made in the USA. The materials and workmanship involved in creating your knife will be done with the utmost care and will be free of defects. 

Paul Bos Heat Treat

We are known for our blades. Buck Knives is a market leader in edge retention thanks to our steel selections and heat treat process pioneered by industry famous, Paul Bos, whose heat treating system has proven to be the best in the business. Each blade is put through a rigorous heat treat process and quality performance test. It is then tempered to the appropriate Rockwell Hardness through a heating, freezing, and reheating system. This gives you longer edge life, ease of resharpening, and a blade that will not fail you.
