I have switched to carrying a utility knife like this one:

No sharpening, cheap blades available just about everywhere. Another option: MOSSY OAK 2-pack Folding Pocket Utility Knife Set, Quick Change Blade, Frame Lock, EDC Box Cutter with Belt Clip, Stone Washed currently on Amazon for $13.99 or $7 each.
If you fly, you toss the blade and pick one up after you arrive at your destination. I still have my Spyderco knives, a Gerber, a CRKT, a Kershaw, and a few others, but for what I do on a day to day with my carry knife, one of the inexpensive utility knives works well for me.
Be safe.
