An OTF Knife, also known as an out-the-front knife, sliding knife, or telescoping knife, is a pocketknife with a blade that opens and closes through a hole in one end of the handle. Contrast this with the majority of knives, which are either standard folding knives or are "fixed blade" sheath knives (having no mechanical operation).
"OTF" only refers to the basic portion of the knife's mechanical operation where the blade slides parallel with the handle to deploy.
OTF knives may be further subdivided into manual sliding knives, which are not restricted as inertia knives, and automatic OTF switchblade knives and gravity knives, which are restricted offensive weapons.
Switchblades and gravity knives provide a great variety of different OTF mechanisms.

Famous quotes containing the words sliding and/or knife:
“With these I would be.
And with water: the waves coming forward, without cessation,
The waves, altered by sand-bars, beds of kelp, miscellaneous
driftwood,
Topped by cross-winds, tugged at by sinuous undercurrents
The tide rustling in, sliding between the ridges of stone,
The tongues of water, creeping in, quietly.”
—Theodore Roethke (1908–1963)
“When she, and though some said she played
I said that she had danced heart’s truth,
Drew a knife to strike him dead,
I could but leave him to his fate;
For, no matter what is said,
They had all that had their hate....”
—William Butler Yeats (1865–1939)
