80.00 is alot of money for a SAK with changeable blades. If you gotta travel then buy something when you get there most sporting goods stores or Walmart or Target will have a decent selection of knives to choose from. Heck the new Leatherman's that are coming out should be around 25.00 at most places you could grab one of those and mail it back to yourself or something. It's a neat gadget but much like some of the 80's era survival tools I think this is doomed to go down in flames.
