Hmmm, I really don't have a dog in this fight since I no longer fly. However, when I did fly before 9-11 I carried a small locking blade in my backpack, not so much to survive after a crash but because that's where I always kept that small folder. The crazies were not a concern. The few times I traveled by air post 9-11 it was always for work, but those requirements are done.

This new TSA decision on knives will not change my attitude on flying in the least. If I can drive, I'll carry a Benchmade 710 as EDC with a .308 bolt gun cased in back. IMO driving is much more pleasant. If I can't drive, I'll reconsider whether I really need to travel at all.
