Ball Bearing Knife Technology
Ball bearing knives are designed for smooth and efficient opening with a reduction in friction for rapid blade deployment.

Liner Lock
A Liner Lock is a folding knife that locks open via a tensioned metal liner inside the handle. Similar to a Lock back, opening the blade activates the lock. Unlocking is achieved by placing the thumb on the front part of the liner and pushing to the left, which releases the blade. Liner locks are typically one hand open, one hand close. A blade thumb stud, flipper, or hole, enables one hand opening.

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.
