The Griptilian family of knives remains one of Benchmade's best-selling and utilitarian designs. All Griptilian models sport an ergonomic, light-weight handle with a high-texture grip great for every-day carry. Benchmade makes a variety of blade types with the Griptilian body, guaranteeing one for every use.

N680 Stainless Steel (HRC 57-59)

A special-application steel for when corrosion resistance is the primary requirement. Ideal for salt water applications, the addition of nitrogen to the alloy gives this the best corrosion resistance of any blade steel, with edge retention between n420HC and 440C.

Over the years, Benchmade has developed a special recipe for heat-treating their blade steels. This process maximizes the steel’s molecular structure for a custom toughness and superior performance.

AXIS® Locking Mechanism

Benchmade's patented AXIS® mechanism 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 that 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.

Drop-Point Blade

Drop point blades slope on the spine from the handle to the tip. This allows the spine of the blade (where the blade is thicker and thus stronger) to continue forward to the tip of the blade. Durable and easy to control, this is a versatile and popular blade style.
