If you are not having frequent run-ins with the law, and do not have a felony criminal background, I would carry whatever knife I felt was needed for what i have to do. Just carry what you want, and don't commit crimes.
Getting caught with a knife of a disallowed length could get me banned from even applying to the bar, much less disbarred completely.
I don't think being forbidden from your entire career is a good tradeoff for carrying something out of spec.
