Made of ultra-strong aircraft aluminum for self-defense; thread designs at the handle and thumb head allow a thumb grip: the optimal way to fully transfer your power to the target; won't break; won't rusk
Lightweight: When detached to function as a ballpoint pen, it weighs half as much as a regular tactical pen, making it practical for daily use; this solves the balance issue
Write smoothly, smear-proof ink, ink quickly dries with a consistent ink flow; compatible with standard 2.75-inch long refills
