Knife law. It is one tricky subject to try and keep oneself updated on. I have found multiple sites and spoken with several individuals (military, police, knifemakers/manufacturers.) and they all have different views as to what is legal. I won't claim to know, since I'm no lawyer and don't know the legislature. But I can tell you that I've found most knives are legal to carry when accompanied by a carry permit. For the low cost and peace of mind, I recommend getting one vs. taking your chances. Below are a couple of sites I found, tell me what you think!
