ABSTRACT:
The present disclosure describes a pocket-knife having a handle. The pocket-knife comprises a front component having a pivotal plate provided with a slot having a recess at each of its extremities, a blade having an extremity to be moved out from the handle, a pin connected to the other extremity of the blade and being adapted to slide along the slot, and a back component forming with the front component a channel with an opening into which said blade can slide. The blade is slid by positioning the pivotal plate in a first position in which the pin can be slid by a user along the slot to move the blade along the channel. The blade is locked outside or inside the handle by positioning the pivotal plate in a second position in which the pin is either located in the recess of the slot adjacent to the opening to lock the blade outside or in the other recess of the slot to lock the blade inside. The pocket-knife also comprises a spring for automatically retracting the blade inside the handle when the pivotal plate is in the first position.
