It is often said that the pen is mightier than the sword, but the Impromptu Tactical Pen from Gerber lives up to that saying and not just in what you can write with it. It features a glass-breaking steel tip that can still “write in the rain” as well as upside down. It is a rugged writing instrument that features a machined steel body that is durable enough to survive just about anywhere.
The video below shows what else this mighty pen can do.
