Ball Bearing Knife Technology
Ball bearing knives are designed for smooth and efficient opening with a reduction in friction for rapid blade deployment.
A Liner Lock is a folding knife that locks open via a tensioned metal liner inside the handle. Similar to a Lockback, 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 thumbstud, 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.
We warranty each and every Buck knife to be free from defects in material and workmanship for the life of the knife, and we will repair or replace with a new knife, at our option, any Buck knife that is defective.

This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.
This blade is full bellied with a strong, thick point for heavier tasks. It can also be used as a general work knife. The top of the blade drops down toward the tip, which minimizes accidental puncturing while skinning. The drop point blade is strong and very versatile.
