Thank-you, all. I figured that anything w/a blade was a no-go. Wasn't sure about Czech tools w/just a poker, the lil' scooper, and tamper. I'm leaving my lighters at home.
Now about my pipe bag (which I need to order asap!!)... How do I prevent it from making everything else in the carry-on smell? And do you guys have preferred (brands/mfrs) pipe bags?? I just have an old Jobey that's too small for multiple pipes. Thanks again, guys!
