I posted on this a while back, which you can read
here.
Despite the vagueness, there is precious little case law to go on.
State v. Myles 1995 did rule that a paring knife carried concealed is in violation of this statute, though Myles did provoke her interaction with police because of her harassing conduct.
You're post was up for less than 2 hours, so I was initially confused why you felt the need to post this. But suffice it to say this sub-forum is not as active as the other parts of the site. Lots of people love knives, but I find not many people know much about law.
