A sharp pencil is provided to prevent the sharp pencil lead from being broken during writing by forming a lead adjuster in a top part of a sharp pencil-case, thereby freely adjusting length of sharp pencil lead discharged from the sharp pencil when pressing a press member. A lead adjuster-formed sharp pencil comprises: a front end cap(10) from which a sharp pencil lead is discharged, and in which a catching projection(11) functioning as a stopper is formed to stop the check and sleeve after moving a chuck(60) and a sleeve as long as a predetermined distance to discharge the sharp pencil lead to the outside while the check and sleeve move forward when a press member(80) is pressed into the sharp pencil; a case(20) having a protrusion(21) formed on an upper end portion thereof; a sharp pencil adjuster(30) of which an inner side is formed in a hexagonal shape; a slider(40) having the sleeve formed on an end portion thereof to stop the chuck when the chuck retrocedes after discharging the sharp pencil lead to the outside; and a spring(70) coupled to the slider to provide the chuck and sleeve with force of restitution such that the chuck and sleeve return to their original positions after receiving pressure. |
