I agree with you completely. Nobody is rolling over though. Was it about a year ago when issue came up, that they wanted to change the law that would make pretty much every knife that could be opened with one hand illegal. A lot of people voiced their protest, lawyers and some politicians helped to get this straightened out. That was the time when we really needed to stand our ground and protect our rights.
On the other hand entertaining our right to carry and use a knife when ever and where ever we please, in any way we see fit, as long as it is legal, might back fire. Turning enough people against our right might swing the vote in other direction next time.
See what happens in New York state. Even without a change in federal law, DA (or whoever is doing it) raided knife stores claiming that most (if not all) locking knives that sell there are illegal. This is very unfair. It would be good, if we could figure out how to fight against this.
On the other hand insisting that you can and will continue using your 4" knife at work, at your own discretion, even if it makes 10 people around you very uncomfortable, simply because it is legal (and they can shove it...) That doesn't do any good at all.
