They say the pen is mightier than the sword, but neither of those implements are really that effective when it comes to starting a campfire. So if survival and copious note-taking are high on your list when it comes to choosing office supplies, consider this tactical pen that hides a fire striker inside.

Made from high-grade aircraft aluminum, the pen unscrews in the middle to reveal a shaft of fire striker inside that can be rubbed against the butt of the pen for an instant shower of sparks. At $45 it's considerably more expensive than a Bic pen and a pack of matches, but could either of those really survive the rigors of outdoor life? Highly unlikely. [ThinkGeek]
