Collet Pen Aluminum - Designed by Joe Wu. Just a pen? Hardly. The Collet Pen is part writing instrument, part precision scribe multitool. Hidden beneath the back cap is a tungsten carbide tip scribe strong enough to mark most hard materials. It’s held in place by a collet chuck that can accept any manner of optional scribe implements.
