why have they all got guns and knives? My God, America is a violent country. Even the Librarian is armed with a knife a taser and a gun to keep off rapists and murderers. The amount of fear in that country must be off the scale that everyone needs to go out the door armed to the teeth.
The knives are for everyday cutting tasks. I carry at least one. Have never considered using it in a self defense situation. It would most likely end up being used against me. Lots of people carry knives. Look up the concept of EDC.
