ABSTRACT:
A mechanical pencil of the collet action type is provided with a lead collet being formed from a pair of identically configured mating shells which are maintained in fixed relation with respect to one another by means of an annulus cooperating with a conical flared portion formed at one end thereof and by means of a cap at the opposite end, all parts of the pencil being maintained in assembled relation by a spring. The parts are assembled by sliding first one and then the other of the two collet shells through an annulus into mating relation with one another and thereafter fitting the end cap over the end of the mating shells.
