While the 5.11 Double Duty Tactical 1.5 Pen doesn’t open handcuffs or feature an integrated flashlight, it makes for one heck of a last ditch self defense weapon should you drop your knife or run out of bullets. The Double Duty 1.5 tactical pen features a machined aerospace grade aluminum construction with a matte black finish, a knurled grip for better handling while taking notes, and a sharp, pointed end for impaling your would-be attacker. $60
