An innovative tactical pen, the Impromptu has been developed by Gerber for a variety of tasks. The casing is made from strong machined steel and features a tempered window-shattering nib which can be used to break car windscreens in an emergency or defend one’s self from danger.

This push-button pen is capable of writing in all-weather with its “Rite in the Rain” ballpoint pen cartridge, effective for both dry and wet conditions. Includes an integrated pen clip for attaching to front pockets for when you need it most.
