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.
It is important to familiarize yourself with local laws regarding knife possession. Certain jurisdictions, such as Japan, may consider knives over a specific length as weapons, even if they are ordinary kitchen knives, when carried in public. Additionally, some types of knives, including dagger knives, are prohibited regardless of their size. If you are found carrying such knives, you could potentially get into legal trouble. However, in certain circumstances, such as when transporting a knife from one location to another, you may be released without prosecution, though it can still be a hassle to go through the process.
