It seems simple enough. You open the knife, you close the knife. But it’s the mechanics of motion that happens in the process of opening and closing that can make the difference between ordinary and extraordinary. Is the knife easy to actuate, can it be opened with one hand, is it ambidextrous, and will it be reliable when you need it most? These are all essential considerations when it comes to knife mechanics.


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. Available in manual, AXIS® Assist or Auto AXIS® configurations.


 Easily opened, quickly and with one hand; this evolution of the AXIS® includes a spring that helps to fire the blade into the open position once the user pushes it beyond a certain point manually. The AXIS® lock also has the added benefit of “suck-back,” which encourages the blade to stay in the closed position. AXIS® Assist knives also feature integrated safety lock systems.


 The basic principle is an integral locking bar within the knife liner being stress-bent, enabling it to spring into position behind the rear tang of the blade when the blade is opened. The locking bar wedges against the rear of the blade, locking it open until you physically push it clear and close the blade (locking-liners are made either right- or left-hand specific). And with a modified locking-liner you get a patented feature that helps to enhance the lock function. The function success and function failure of a locking-liner depends greatly on how well it is made and also the quality of the materials used. With Benchmade, you get both.


 The monolock mechanism is basically a locking-liner on steroids. The knife liner is one in the same as the knife handle and thus it is designed and made to function as the locking mechanism. Subsequently, a thicker material is used to provide enough surface area to be a functional handle and in turn creates a larger surface area to lock the blade with. If executed properly, the monolock design rates very highly in strength and function.


 Built from the framework of the locking-liner with some innovative updates. The lock engages using tensile strength, compared to the compression hold of more traditional locking-liners. With the Nak-Lok®, the possibility of personal injury is greatly reduced with the opening finger never crossing the blade's path.


 Another patented Benchmade exclusive, the Nitrous® boosts the blade with ease. As the blade is closed, the two torsion arms that run the length of the handle liners are secured in place and make contact with the blade tang. As tensioned against the blade tang, the user rotates the blade open to a 30-degree angle, the torsion arms take over and continue the blade opening process on its own. The huge advantage to the Nitrous® design over other similar concepts is that the blade must be rotated open to beyond a 30-degree angle which offers added user control.


As much an art form as it is the ultimate example of form following function. The Bali-Song, or butterfly knife, is of Filipino ancestry dating back to nearly AD 800. Its basic form consists of a pin-hinged, two-piece handle which when closed encases the blade for carry. Opening and closing can be accomplished with a single hand, making the tool that much more utility capable.


 Sometimes restricted to Active Duty Military, Law Enforcement and Public Safety, these automatic knives utilize either push-button, slide-release, or dual-action mechanisms. Benchmade autos take full advantage of powerful springs coupled with our precisely machined lock mechanisms, providing the most reliable automatic systems available in the industry. Our patented integrated safety mechanism, located on the handle spine in all push-button automatics, ensures that the blade will not inadvertently deploy or close once it is locked open.
Auto AXIS® — Strong, reliable, fast, and AXIS® lock through and through, this locking mechanism fires the blade open 100% mechanically when the AXIS® bar is pulled downwards. Auto AXIS® also features integrated safety mechanisms and the added safety of “suck-back.”
Dual-action knives come in multiple forms, but only one group features the strength and ambidextrous versatility of the AXIS® lock. The AXIS® dual-action automatic mechanism allows the user to open the knife like a regular AXIS®, but there's a secret. Pull the AXIS® bar further down in its stroke and a spring takes over and fires the blade automatically.
Push the button and the blade fires into the open position. Our push-button mechanisms are not only fast and convenient, they are extremely strong. Most also feature integrated safety mechanisms.
While push-button automatics have traditionally been single sided, Benchmade also has ambidextrous push-button autos that feature push-buttons on both sides.

Our OTF mechanisms are mechanical masterpieces. Slide the lock button towards the top and the blade fires straight out. Pull the button back to the bottom and the blade returns to the handle.
