Abstract
A twist retractable writing implement wherein a cap threadably engages a barrel and supports a scribe element, rotation of said cap longitudinally displaces said scribe element with reference to the barrel alternatively into extended and retracted condition. An internally grooved annular flange with a tapered base forms a socket for mounting the scribe element to the cap and provides an air passageway to the seated end thereof. A non-circular bore adjacent the opening tip of the barrel receives the writing tip of the scribe element while providing an air passageway into the barrel.
