Nice pics.

The thought of sgian dubhs on cruises was discussed by a bunch of us on a cruise forum I used to post on regularly. Most agreed that based on the fairly broad definitions in the cruise line weapons policy, that they would not be allowed. One poster told of how she found actual mention of sgian dubhs in that policy, but I followed her links and never found it. I still have a feeling that it wouldn't make it past security, and have no desire to loose even my cheapest of sgian dubhs.

As for the sgian brew "looking like" a knife, I have encountered that sort of on a cruise, although going way off topic here. I was on a Carnival Cruise and they were taking anything that looked like a weapon, even obvious plastic toys that kids were bringing back from port. The cruise was showing Rocky Horror one night and a group of us set about getting the required props when we stopped in Grand Cayman. In order to get squirt guns that did not look like real ones we had to get ones that looked like frogs.
