I live a dull life, rarely straying from civilisation, and the chances of me being in a survival situation are virtually nil. Flying is the one time I do have a chance of being marooned somewhere too remote for instant rescue. That is when I'd most want to have a knife.

I don't agree that a little knife is useless. We've debated this before. For some tasks, like splitting logs, you need a big one, but there are a lot of jobs you can do with a small knife that you couldn't do at all without one. At least if it is a good small knife - I don't know the product in question.

Although I wouldn't advise anyone to try to circumvent the law, when the rules are bad subversion and civil resistance become possible moral options.

If on the day you decide not to risk it, just transfer the knife to your checked-in luggage.
