CRKT Collet Pen TPENWU Aluminium, tactical pen

The CRKT Collet Pen: just a pen? Hardly. The Collet Pen is part writing instrument, part precision scratch-pen. Hidden underneath the bottom cover is a tip made of tungsten carbide. This is strong enough to mark most hard materials. It is held in place by a collet that can work with all kinds of optional writing tools.
