Abstract
A multi-purpose folding tool including a pair of folding scissors, in which a scissors blade is movable about a pivot shaft, between a stowed position and a deployed position in which a stop prevents the blade from moving further with respect to the handle because of pressure on the handle in the direction needed to close the scissors blades in a cutting stroke. A rocker is moved by a spring in the tool handle and which in turn urges a movable scissors blade toward an open position. In one embodiment two handles are folded about respective scissors blades to house the blades, and four springs hold the handles together with the folded scissors stowed within the handles. When the blades are deployed one of the springs holds each blade in position with respect to the handle while the other spring urges the blades toward an open position, through action of a rocker. When the scissors and other tools are folded into their stowed positions in the handle of the multi-purpose tool of the invention the tool has a smooth outside configuration allowing the tool to be carried in a pocket without causing undue wear.
