Funny to see postings from guys who are supposed to know that anything that looks like it will do harm, must go in checked baggage. There you take your chances.
Great tool for sure and not that expensive but if you have to do any flying that requires a security check, your gonna get hammered for having such things. Pilot or Coach seat.
I have forgetton to remove mine recently in the states,but we now have a commercial operator who has available a system where they take your knife, leatherman etc and place it in a locked box with your name and mailing info on it along with Credit Card info and its mailed to your home for a reasonable fee. Saves massive replacement costs.
By the way the latest price for the Leatherman tool (18 tools) with a refilable Butane Lighter and Binoculars (package) is R420 in the states, given the Rand fluctuation.
