ABSTRACT:
A penpoint has a base portion and a plurality of comb-tooth pieces and a converging member fitted over the portion of the penpoint body between the base portion and the comb-tooth pieces. The uniform pressure of the converging member converges the comb-tooth pieces front ends into an undistorted hemispheric writing portion having ink passages between the adjoining comb-tooth pieces. When the penpoint is pressed against paper with the pen axis inclined, the front ends of the comb-tooth pieces shift and elastically deform to expand the outer diameter of the hemispheric portion. When pressure is relieved it returns to its original hemispherical shape. The thickness of strokes varies according to writing pressure. The penpoint can write in any direction.
