I travel a lot,,,,here's what works.
1. Tupperware or Herf A Dor......
2. Bic lighter or any lighter that is a flint/soft flame
3. Cheap Cutter
4. Copy of what is ok to put in your carry on per TSA Rules ( this has saved me those little arguments with a TSA Agent who wants to debate their own policies )
NEVER bring your expensive soft flame lighter on a trip unless you can afford to have it confiscated
Checked baggage does not guarantee that your "stuff" will make it through.....I've had lighters, cigars, cutters taken with a little note inside my checked luggage that said my contents have been taken.....even the unbanded cigars were taken and I assume were smoked by the TSA crew and used my $80 lighter.
