I've always carried a collapsible corkscrew in my bag - got pulled for it because it looked like a detonator but no confiscation in the end.
Also got pulled for having real razor blades, not disposables and confiscated.
I try to remember to leave my little swiss army knife, the one with the scissors, nail file and small blade, at home but it has seen Morocco a few times - the last time via Spain.

there I go again
not too hard really
