This is cool to bring always because not only can you protect yourself by pretending it’s a gangster knife, but at the same time serves as a Butterfly Knife-Styled Space Pen. Because of that characteristic alone, with practice you can learn more sophisticated moves, two-handed tricks, quick-flips, spins, aerials, and how to manipulate combinations of these tricks. This is also durable because it’s made of polymer in three pieces. There’s also dynamics on how this was made that’s why it’s perfect to do tricks with it just like the real knife! As for the pen, it’s of nice quality since it’s a Fisher Space Pen which is capable of writing under water, upside down, in freezing cold and other conditions. Ain’t that great? $35.

Here’s an idea: what if the pen is the mighty sword? Then what you’ve got is the perfect weapon, one that can document your exploits and another that can help you attack in close quarter combat. The Benchmark 1100 Pen may look like an ordinary writing tool but it is also a pointed Kubotan (small stick) weapon. One end is the ball point, the other is the business end of a sharp weapon designed for striking various kill points. Machined aluminum or stainless steel body guarantees toughness and all made in the USA. $120.

SureFire Pen

This thing is anything you could ever ask for in a pen and then some. Made aerospace-grade aluminum, that is hard-anodized, you could run this thing over with your truck, and I would personally be more concerned for your vehicle. It accepts just about any ink cartridge that you throw at it, and the back end of the pen is strong enough to break through glass for those long nights where you can’t decide between a relaxing night at home writing your memoirs, or an exciting bank robbery. $125.
