![]() Our superb quality knives will leave you awestruck.For the uninformed, OTF knives are a type of switchblade – that is, an automatic knife which deploys the blade ‘automatically’ on pressing a button or switch. If you want to purchase the the best quality knives, must visit our shop section and look through the military tactical knives, and automatic OTF knives. As a result, most OTF knives are not too novelty, unsuitable for tactical operations and serious work requiring a stiff knife. Usually, there could be only one and at most two connection points or ranges between the handle and the blade. ![]() As a result, OTF knives are notoriously weak, and the blade is prone to wobbling when the edge is in the open position.Īlthough OTF knives include a lock to secure the blade in the open position, the buckle provides relatively little support for the blade. Indeed, in most OTF knives, the blade moves freely in the handle, at least at some point during the opening and closing motion. OTF knives completely lack the pivot pin's main stabilizing feature of folding knives. This causes unwanted wear on parts, including the blade's sharp edges. As a result, when the blade is brought into the open position, it actually moves in a winding path. Usually, the trigger mechanism of the OTF is located on either side of the spring mechanism. With these systems, the user manually loads the spring, and this load is transferred to the blade when the trigger is activated. The second most common system used a "mechanical" reloading system similar in design to the crossbow. ![]() These systems use a trigger to apply a spring force to the blade. The first system is sometimes called the "shuttle" system. There are two basic spring mechanisms used in the best automatic knives. OTF knives usually use a spring mechanism to pull out the blade from the closed to the open position. As a result, the blade is held very firmly in the open position with slight blade oscillation relative to the handle. We conclude that whether a folding knife has two or three of these connection points or "planes", the blade is very firmly fixed to the handle. Then, a lock secures the edge in the open position, which is essential to release to move the blade in the closed or folded position. In addition, many folding knives have a third strong connection point between the blade and the handle. These two solid connections between the handle and the blade create folding knives with a solid blade handle structure. The latter contacts the blade's tang and stops the blade's rotation when the blade is responsible for rotating into the open position. The first point of connection is the quite solid connection between the handle and the blade, whereas the second is between the blade's tang and a blade stop pin in the hold. It is mainly because folding knives have two solid connection points between the handle and the blade. Extended and extended positions make them more vulnerable. ![]() A second latch arm engages the edge when it is in the open position.īy comparing OTF knives with folding knives, we have concluded that OTF knives are inherently weaker than folding knives.An opening blade lock consists of a first latch arm capable of engaging the edge, and.Blade stops are responsible for preventing blade movement when the blade is open.Within the handle, there is a longitudinally sliding blade, one for closing, one for opening.Then there is a front end, a back end, and an opening into the space through the front end.a handle that further includes a first handle side wall and a second handle side wall.Postscriptum, Stiletto is the name of a blade style that has dual sharpened edges. Manufacturers commonly use stiletto blades in the making of the best OTF knives. People often mistakenly refer to them as Stiletto knives. But these "out-the-front" knives, referred to herein as "OTF" knives, can slide linearly. If we talk about other knives, they can slide longitudinally to open or close the blades. This invention refers to knives having automatic-opening blades, specifically "out-the-front" knives with blades that open and close by sliding longitudinally and lineraly into and out of the front of the handle. It incorporates an access port for cleaning or maintaining the internal components of the handle, which manufacturers substantially enclose with the handle. Blade guide systems are responsible for the blade's longitudinal or linear movements. OTF knives mean out-the-front knives, which means a single trigger is enough to open the knife and close the knife automatically.Įvery knife comes with a separate firing and unique retraction spring to vary the speed and strength of the blade. When your knife is locked in the open position, it will define a 3 point blade-handle interconnection between the blade and the handle. An OTF automatic knife integrates dual locking and release mechanisms.
