ABSTRACT:
A conical penpoint is disclosed which resiliently deflects at its end by the pressure of writing to allow the thickness of written lines to be varied easily. The conical penpoint comprises: a penpoint body having a cylindrical base portion and a conical portion formed of a plurality of comb-tooth pieces continuous to and extending forwardly from the base portion; and an ink supply core installed inside the penpoint body and extending longitudinally therein. The front ends of the comb-tooth pieces are joined together so that the front ends of the adjacent comb-tooth pieces are in resilient contact with each other. When the apex portion formed by the joined front ends of the comb-tooth pieces is pressed against paper with its axis at an angle with respect to the paper, the penpoint elastically deforms allowing the thickness of written lines to be varied.
