.375 Bullet Pen
The person that said that the pen was mightier than the sword, obviously didn’t know about the Fisher Space Pen. It’s made from a real deal .375 caliber bullet and probably isn’t best for those of you that do a fair bit of airplane travel.
If you’re wondering how it works, the bullet portion, not the casing that would contain the gun powder, unscrews from the casing to reveal the ball point pen. After being unscrewed it can be reinserted into the casing to make for a longer pen, ideal for those with larger hands.
You can pick one up for $25.
