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

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.

Frame Lock
A frame lock functions like a liner lock, but the locking mechanism is a section of the handle “frame”—on the side of the knife. The “frame lock” is a channeled lock arm that moves inward to lock against the blade when the knife is opened. Pushing outward releases it from its “locked position” so the user can close the blade. Benefits are fewer moving parts and lighter weight. Frame locks are typically 1-hand open, 1-hand close.

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.
