The Gerber multitool is a must overseas, I must have like 5 of those things. It was my most used tool, for everything from cleaning weapons, opening MRE's, whatever you would need a tool for........ Broke most of the attachments eventually prying on things, etc. I still use them once in a while.
84CJ's post reminds me of how I had to throw my nice little Mako automatic folder in a dumpster on the way out of Iraq, because it wasn't worth the hassle to get the letter. I also collected Zippo lighters and the Customs people made me take the cotton out of about 10 Zippos and other lighters I had

Basically ruined about $500 worth of nice brass Zippos I had sent over in the mail. I also had a few nice vintage Ronsons I got on FleaBay that were destroyed too........ridiculous.
