I know this is a late time to bring this up, but wasn't there a writer to a blade magazine (these articles are in the front pages) that proffered automatic knives were now legal in all fifty states?
The idea was that since the "law" was now recognized in all fifty states, folding knives (including automatic knives) were also grandfathered in by the new statute.
I was once having coffee in the beverage shop of 'Barnes & Noble' when I noticed a police officer was taking a break, as well. He asked me what I did, and I just mentioned "salesman." Then I grinned and handed over a 'sample.'
He never said a word. He clicked open the knife, asked about pricing and then handed me back the folder. He then told me something I had not heard. Supposedly the statute of automatic knives was technically still on the books--but he also added that, "so is still jay-walking." The hassle it would take him and his partner to arrest, search, send for a squad car and then book a citizen for a "knife" would cost several times their wages over an arrest of a peaceful citizen.
However, the more I asked several sources I found that "knives were legal in Wisconsin," while others said "knives are not legal" in some places of Wisconsin.
Of course, I once found out that a police officer became my new neighbor. I walked directly to his house, welcomed him and his family to the neighborhood and showed him some of my samples. We had a nice chat, and he handed all the "illegal knives" back to me.
The background on this was pretty simple. In conversations the officers admitted that if a guy was sitting drinking coffee and opening his mail with a switchblade they would just ignore the issue. However, if a guy pulled a switchblade on a citizen, then the attacker would be arrested for "drawing a weapon." Same knife, differing circumstances.
To that, I think opinions in Wisconsin have gotten more slack. Just a few years ago a switchblade in any circumstances would get you tossed to the ground and handcuffed. Now senior citizens like me are viewed with possession of a "simple letter opener."
Funny how times change. You open a switchblade in public and nobody cares. You harangue a lurker over the internet and you could do some serious time.
And here's a laugh--I have double-jointed thumbs. Technically, I could apply--and receive--for some form of abnormality on my Wisconsin Drivers' License. I have no problem at all activating the buttons and levers in my truck, along with any lever of an automatic knife. But like I said, this is Wisconsin. This means that 'handicapped is handicapped.'
