showing them the axe
What sort of plane are you flying that you not only have an axe on board, but also (presumably) the room to swing it around?
Most of the aircraft I've flown didn't even have a first aid kit nor a fire extinguisher and to be honest, I've never cared about them. Both are likely going to be as small as the regulations allow, which means they're useless in an actual emergency - not to mention past the expiration date by then.
