(noun)

retractable small blades on a *d'k tagh* knife

(skybox card)

The Klingon battle knife is designed primarily for versatility of use, so that the user is never caught at a disadvantage. Two small, secondary blades eject from the knife's sides, providing both a hand guard and another set of cutting edges. A brutally spiked pommel fastens the hilt together to provide a damaging surprise attack or give a devastating backhand stroke.
