6. Lipstick Knife

Again we come across a weapon that was cleverly designed for the ladies, and could be useful in one of those desperate situations when no other options is available. The only problem is that this lipstick knife has a blade that is about an inch long. It’s probably not long enough to reach any vital organs, but if applied skillfully to the eyes or neck, it could be enough to stop a rapist in his tracks. From what we have heard about Detroit, where this item was discovered, it would be hard to blame a lady for packing one of these in her purse on a regular basis.
