U.S. airports are very tool-unfriendly these days. Based on my experience, the scissors, steel wire, wire saw, and razor are definite no-nos. I saw a woman sewing in the Salt Lake City airport just after the Olympics and expressed my surprise that she was able to get her needles past secuity. She said they didn't bother her about the needles. That may depend on the individual airport. Shouldn't be that way, but it seems like it is. I can't answer about the syringe. Also, it would be interesting to see how they treat the Altoids box itself, as it goes thru the x-ray machine and shows up as an opaque rectangle.<br><br>Good luck.<br><br>Alan
