The pen is indeed mighty and none mightier than the BATTLBOX Tactical Pen. This is our new favorite pen at READYMAN and considered "essential" EDC (Every Day Carry) gear.
The pen writes smoothly, consistently and uses standard refills available at any office supply store. It is the perfect size; not to big, not too small and it's machined from premium aluminum and hard coat anodized for hard use. The pen features a carbide glass breaker tip for emergency use on hard surfaces (or soft).
This pen can be legally carried on a flight for taking notes or personal defense.
