I'd bring a small, inexpensive mutitool; carefully.
I went on a cruise a few years ago and brought my Schrade Tough tool. It went through two international airports in my checked luggage then onto the boat without issue. Coming back from one of the islands we stopped at (eastern Caribbean) we got held up as we were boarding the ship as the 115 pound "security officer guy kept scanning my wife's bag and not saying anything to us.
He finally gestures to the bag (which was a clear plastic beach bag BTW) to open it and remove all contents so I grabbed it and basically dumped it on the xray scanner belt wherein the security dude starts going through everything.
At this point I was getting a bit worried as I had thought someone stuck drugs in our bag or some other contraband and didn't even think of the multitool I had dropped into the bag in the morning when we left.
Finally, the security guy holds up the pouch between two fingers with the schrade tough tool in it as if it was some sort of nuclear device asking "what's this?" and I respond "a multitool". Confused; he calls up some back up to assess the situation. :foot:
The group of the three or four brain trust security spec op's team members deliberate and decide that pliers are not a threat, nor am I and let us on our way. The irony is that right behind them the entire time is signage saying that scissors with less than 6" blades are A-okay to come aboard but they gave us a hard time about a multitool with a 2 1/2" blade that is a beyotch to open even two handed.
I wish I had taken a picture of that sign and the security guy's face... :foot:
