There is inexplicable silliness in some of the logic of securtiy.

I walk with (2) aluminum canes. Each can be used with great effect as an impact weapon and even though they are not pointed and have rubber tips on the bottom, they can be shoved into sensitive parts of the body. The poltential is there even though they are not designed for such use, but a small key chain style kuboton is forbidden because of its designed use.
