A writing instrument cum self-defense tool, the Titan Pen can save your ass in the office and the streets. Machine from titanium from tip to base, it features a standard Parker style cartridge for taking notes, and a tungsten-reinforced attack tip capable of shattering wind shield or fending off an attacker. The built-in ceramic treated clip on the snap cap attaches to any note pad, bag or pocket protector so you’ll always have this life saver when you need it.
