Hence "feasible". I can also bring a knife roll through airports, as long as it's checked in. And if I'm on the road full-time I imagine I've got something else that I couldn't carry on anyway. Or I might consider the extra hassle of checking luggage in to be worth having my knives on me. I try to travel carry-on only as much as I can and I could definitely see myself preferring to bring my knives.
