In the pipe sliding type sharp pencil, a tapered holding surface at a predetermined angle is formed on the inner surface of the tip, and when the guide pipe having a breaker function moves forward together with the pencil lead by operating the knob, the tapered holding surface is formed at the rear end of the guide pipe. A pipe slide type sharpening pencil characterized in that the corner edge of the large diameter proximal end bits into the tapered holding surface and is weakly held.
