The Benchmade 111H2O-BLK Bullhead Axis Lock Dive Knife Black Satin Plain new water knives offer great corrosion resistance, cutting ability and edge retention. The H2O Folding Sheep s-Foot Knife has an AXIS locking mechanism, N680 stainless steel blade with a 57-59HRC hardness and a modified Sheep s-Foot ambidextrous thumb-stud opener. The AXIS Locking Mechanism is 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 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.
N680 is a chromium-molybdenum conventionally produced stainless steel with the addition of vanadium and nitrogen. Excellent corrosion resistance properties, especially in saltwater. Good hardenability and high obtainable hardness. High wear resistance and ability to preserve keenness. The knife s handle is grivory scales an amorphous nylon copolymer with exceptional dimensional stability. 50% or greater glass fill for a sure grip. The knife has a Modified Sheep s- Foot Blade Style. This blade shape has no point on the tip, very little to no belly and the spine of the blade curves down to meet the edge. It is used in applications where slicing is the main requirement, and a point is either not needed or would actively get in the way. Emergency rescue blades are usually of this design. The lack of a point prevents the rescuer from inadvertently injuring a victim who is being cut free from something restrictive.
