An irony: I recently traveled on Southwest, and they (of course) confiscated my lighters. I was also carrying not one but two cheap cutters.

When they took my lighters, I actually asked "what about these?"

They had no problem with the razor blades I was carrying. But apparently the lighters were a major safety hazard? Very wierd.

Bottom line - I'd go with pre-cutting the cigars. I always use that option. Means I don't have ot carry a cutter with me, and it makes it easier to share a cigar with a novice. And if you don't smoke 'em, cut cigars will age just fine in your humidor, no matter what the magazines say.
