ES295362U - Perfected knife (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved knife, which is constituted by the combination of a blade and a handle, properly joined together, blade in which both edges are operative, essentially characterized in that the said handle, at its emergency end of the blade, has a projection laterally flattened in transverse direction with respect to the axis of the knife, in which is defined, in correspondence with one of the cutting edges and perpendicular to the latter a rib of isoscellic trapezoidal profile, diverging towards its free end, intended for the selective coupling of a complementary piece, provided in turn with a groove formally and dimensionally coincident with said rib, establishing between the two elements a "dovetail" slide, emerging from this complementary piece. An arm, of considerable length, parallel to the blade of the knife and with adjustable distance with respect to the latter, by displacement of the complementary piece on the rib established in the handle, provided that said arm can be rigidly fixed in any position of distancing with respect to the blade, with the collaboration of a prisoner established in the complementary piece from which said arm emerges, and which impinges on the nerve of the handle, being in turn susceptible to this assembly, complementary piece-arm, of being completely uncoupled the handle of the knife, transforming the latter into a conventional knife.
