Abstract
Knives ( ) each include a handle ( ) having a blade ( ) pivotally attached to the handle. The blade is movable between a closed position in which it is received within a groove ( ) of the handle and an open position. The blade has a working portion ( ) and a tang portion ( ), which remains within the groove when the blade is in its open position. A locking pin ( ) extends transversely of the handle and blade and is movable along a pair of elongated openings ( ), and engages the tang portion ( ) of the blade to lock the blade in its open position. A spring ( ) biases the locking pin toward the tang. In another tool ( ), multiple tool blades ( and ) are provided in a handle ( ) defining a wider groove ( ), and a locking pin ( ) movable along elongate openings ( ) can lock a selected tool blade in an open position. A pair of the handles ( ) can be attached pivotally to handle stubs ( ) of a pair of pliers, using the same sort of locking mechanism. An automatic opening mechanism in another tool utilizes a pair of coiled springs that urge a blade into an open position. A locking member locks the blade in the open and closed positions.
