Learn to play the game, but know the rules.
Yup, looks like the same mish-mash as here in Wisconsin. They make everything illegal to catch people with the widest net possible, and the cite exemptions which are often ignored.
It is illegal to carry a switchblade in Wisconsin. I do so everyday. Oh, the police know about it. I sell switchblades to the police because I sought for, fought for and ultimately bought a license to do so.
You'll notice that these laws have disclaimers. Make sure you have your license, if applicable and a copy of the up-to-date statutes with you. Mine are in my supply case, and carried daily 24/7.
I can carry samples. I can carry at work. I can carry to and from work.
Hence, being an 'itinerant knife salesman,' I am always on my way to a client, leaving a client, or at work with a client.
I once walked, in the open with four boxes of switchblades, down the block to the house of a new neighbor, a local police officer. He had done some research (the debate continues in Wisconsin as to whether automatics are legal for all police, no police or just police with permission) and admitted that I can just about sleep with a switchblade and have it legal.
However, Spiderman once told me that with great power comes great responsibility.
I never flash the knife(s)--unless you might be an aggressor and snatch a glimpse of it at the last moment--nor do I carry junk, arm gang-bangers or aid people on how to evade just laws.
I sell to police, fire, EMS and soldiers. I once sold to the father of a soldier who made the knife a gift at a going away party--to Iraq.
Heck, you want to bust me for a 'straw purchase' to a concerned father. Go ahead. We'll be happy to tell the judge why I did it--and where the knife is now.
