they're just convenient and small. I would have no problem with a plastic garbage can full of hunting knives, machetes, etc at every bording gate, and every pax picked up whatever he wanted, and dropped off when he deplaned.why are we obsessed with guns?
Quarterstaffs, morningstars and battle-axes sound neat at first, but they might be difficult to stow under the seat or in the overhead baggage compartment.
