Abstract: Disclosed is a pocket-knife mainly including a handle consisting of two side members which together define a cavity at one side of the handle to receive a blade therein. The blade is pivotally connected at a rear portion to a front portion of the handle by a pivotal pin and can be extended from the handle to an open or operative position or be folded toward the handle to a closed or storage position. A releasable locking means is disposed between the two side members for locking the blade in the open position. The pocket-knife is characterized in several rotatable balls spaced around the pivotal pin and contacting with side surfaces of the rear portion of the blade, allowing the blade to be smoothly extended or folded with help of the rotatable balls.

Abstract: Disclosed is a folding knife with laser indicator mainly including two cases, a blade, and a laser indicating means. The laser indicating means includes a supporting plate pivotally connected to and between the two cases. A long recess is formed in the supporting plate to receive a springy conductive plate, a laser emitter, and a series of cells therein. The laser emitter has a laser diode and a focusing lens in it and has a spring provided to its inner end to contact with one pole of the cells. The conductive plate extends along an inner wall of the recess and has one end contacting with another pole of the cells and the other end extending to a point near an electrical contact of the laser emitter, such that a depression of a push button provided on an outer wall of the supporting plate shall press the conductive plate against the electrical contact of the laser emitter, electrically connecting the laser diode to emit light beam which passes through a hole formed at an outer end of the supporting plate.

Abstract: Disclosed is a knife with lighting fixture which mainly consists of a pair of cases, a pivotally turnable knife, and a pivotally turnable supporting plate. The supporting plate has a cell, a bulb, and a push button supported thereon. The push button is slightly projected from one of the case so that a depression of it may lighten the bulb to shine toward the knife for convenient use in a dark place. The supporting plate may be easily turned out of the cases for mounting a new cell and/or a new bulb when necessary.
