OTF knife

An “Out The Front” knife (also known as an OTF knife) is a specific type of pocketknife. Its defining feature is the way the blade deploys and retracts. With a traditional pocketknife, a user typically opens and closes the blade by folding it into the handle or pulling it out of it. By contrast, the “Out The Front” knife operates a different way. Its blade, when it is in its closed position, is housed in a slot that is fixed at the front end of the knife’s handle. The blade is “out the front” of that handle when a user uses a thumb, say, to push the blade out.

How and why do things happen? That is the fundamental question behind all scientific inquiry. For what purpose do the different parts of a system cooperate to achieve a certain effect? What is the cause and what is the effect? There is a long-standing—and often embattled—commitment of engineers, physical scientists, and biological scientists to answer these sorts of questions in terms of mechanism. To explain a phenomenon means to present a plausible and detailed story that accounts for a set of facts, and it is much to be preferred over simply characterizing the phenomenon in question.

Two primary kinds of OTF knives exist. Single-action OTF knives utilize a spring to open up the blade, and the user has to manually slide the blade back into the knife’s handle. Double-action OTF knives open and close using the same switch; they can open and retract the blade with the press of a button. When the blade is fully extended, the interior mechanism locks the blade into the open position. The blade will not close unless the user presses the retraction button. The retraction mechanism stores energy for the quick return of the blade into the handle when the user wants to close the knife. The system of springs, tracks, and locking features inside the handle ensures the safety of the user during the opening and closing of the knife.

One can safely say that OTF knives are truly masterpieces of mechanical craftsmanship, inside and out.
