Agree that old cut throat blades etc should not be allowed onboard. Just wonder what would happen if someone decides to take the crash-axe with to the hotel and check in with it the next morning in the hand-luggage?
Security-officers would probably go out of their minds stating that due to security reasons that would have to be left behind together with the shaving-equipment. Would be interesting to see their reactions when telling them that due to security reason the axe has to go onboard.
Security is all very good and necessary, but has to make sence and not made up by some office-rat who don't know anything about what can cause damage and not.
