M390 Super Steel
A high performance blade steel with superior cutting ability and wear resistance due to its high concentration of vanadium and chromium carbides. Its unique powder metallurgical process also promotes a uniform carbide distribution and clean steel properties, making M390 a popular steel used in surgical cutting instruments and in applications requiring a high finish. As a blade material it offers excellent corrosion resistance due to its high concentration of Chromium.
Drop-Point Ambidextrous Thumb-Studs
A slow convex-curved drop in the point characterizes a drop-point blade. The drop-point format lowers the point for control but adds strength to the tip. Usually coupled with plenty of belly for slicing, this format is often used for hunting knives. It is also a fantastic all-around blade format. This blade shape can be found on a wide array of knives.
Axis Locking
A patented Benchmade exclusive, AXIS has been turning heads and winning fans ever since its introduction. A 100-percent ambidextrous design, AXIS gets its function from a small, hardened steel bar which rides forward and back in a slot machined into both steel liners. The bar extends to both sides of the knife, spans the liners, and is positioned over the rear of the blade. It engages a ramped, tang portion of the knife blade when it is opened. Two omega style springs, one on each liner, give the locking bar its inertia to engage the knife tang. As a result, the tang is wedged solidly between a sizable stop pin and the AXIS bar itself.
