Benchmade Professional Catalog 2009 - (Page 41) LoCK BACK A basic functional lock that is relatively simple and this is low-cost to manufacture. In practice, the lock design positions a stop bar parallel to and in direct line with the blade at the upper back or rear tang of the blade to lock the blade open. To release the lock, the exposed portion of the stop bar in the handle back is depressed into the handle, pivoting the stop bar out, and releasing the locked blade. This style of mechanism requires two hands to safely close the blade although you may still easily open the blade single-handedly if desired. MoNoLoCK The monolock mechanism is basically a locking-liner on steroids. The knife liner is one and the same as the knife handle, and thus it is designed and made to function as the locking mechanism. A thicker material is used to provide enough surface area to be a functional handle, and in turn creates a larger surface area with which to lock the blade. If executed properly, the monolock design rates very highly in strength and function. oPTIMISER ® Another patented Benchmade exclusive, which “optimizes” the knife mechanism if the user chooses to do so. A steel torsion bar running the length of the inside handle spine is secured in place and contacts a surface area of the blade tang. As the blade is closed, the torsion bar is tensioned against the blade tang. Then, as the user rotates the blade open to a 30-degree angle, the torsion bar takes over and continues the blade opening process on its own. The huge advantages of the Optimiser design over other similar concepts is that the blade must be rotated open to beyond a 30-degree angle, which offers added user control. And even more amazing, the Optimiser can be added or removed at the discretion of the user and the knife/mechanism still functions normally. The choice is yours. BENCHMADE KNIFE CO. 41
