No, I carry mine in checked luggage. And if a reasonable lockback folder is allowed I will carry something inexpensive along with the Leatherman. I have a few older folders that I can carry and not be too hurt if they are lost or stolen. I suppose that is a good use for an Enlan or Byrd.
I intended to add this to the original post too: I don't do much business travel these days but I've made a couple of 1-day trips with associates under circumstances where I couldn't check bags so I had to go for the day without a knife.
