Paradigm Shift Automatic 591 

The bolster locking mechanism/release system is the namesake of this knife, as the blade releases cleanly with an easy push of the brown Cerakote coated bolster. Another new Buck automatic knife, the Paradigm Shift is a great option for someone interested in quick one-hand openers with premium steel, a strong lock and a rugged, yet modern look.

Message from Buck: 

"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 Harness through a heating, freezing, and reheating system. This gives you a longer edge life, ease of re-sharpening, and a blade that will not fail you."
