Its durable aerospace aluminum construction features a subdued matte black finish, with a knurled grip to help you confidently subdue a would-be assailant, if the occasion should call for it.
But this last-ditch self-defense weapon is actually a great writing implement as well, with a Fisher Space Pen PR4 Medium Point Black ink cartridge. It writes upside down, underwater and 3 1/2 times longer than the average ball point cartridge.
With just one color and one size, this mighty pen is available on 5.11's site for $60. For one reason or another, you'll be glad you carry it everyday.
