Pantographic Knife

Function

In this illustration:

Figure A shows the closed knife, with blade retracted.
Figure B shows the pantographic legs opening. The collar is shown sliding down the blade.
Figure C shows the blade almost extended.
And finally, Figure D shows the pantographic legs folded together, making a handle that is half as long as when the knife was closed.

Operating this mechanism is complex, and not easily done one-handed.

Famous quotes containing the word function:

“We are thus able to distinguish thinking as the function which is to a large extent linguistic.”
—Benjamin Lee Whorf (1897–1934)

“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)

“It is not the function of our Government to keep the citizen from falling into error; it is the function of the citizen to keep the Government from falling into error.”
—Robert H. [Houghwout] Jackson (1892–1954)
