The Seattle Center is the site of the 1962 World's Fair and on the northern edge of the downtown area-- six miles inside the cty limits. I assume the difference in regulations was clerical and a court would throw it out if the issue was pressed. I thought it was interesting to note and illustrate the sloppiness in lawmaking. I am certainly no legal professional and I spotted it. The variables between counties and municipalities makes it even more bizzarre, where six feet over a political boundary could make you a criminal.
I was using a neck knife as an example, as many kneck knife blades are smaller than 3.5". The Seattle laws prohibit carrying a fixed blade of any kind, regardless of length, and allow folders up to 3.5". I think the distinction is a waste of time. Like I said, if you get stuck with a 3.5" folder, you will bleed that same as if you got stuck with a 3.5" fixed blade.
Bottom line, most people don't think about protecting themselves and anyone who enters into the politics of it ends up looking like a paranoid case. What method if denial people use when reading history or the daily newspaper is beyond me.
I walked out of work the other day and a gomer was going through the outside ashtray for cigarette butts. I *looked* at him as I walked out the door and he went beserk on me, cussing and screaming and waving his arms around. He called me a faggot, which made me laugh and that really got him going. He flollowed me to the crosswalk, cussing all the way and when I stopped for the light, he charged me. He stopped short when I offered to share 3.5" of very legal and razor sharp Casper-designed stainless steel with his right eye socket (he found out I'm left handed). He took off, calling me a queer because I wouldn't fight with my fists and had to rely on a knife. The guy standing next to me at the crosswalk said, "Dude, I thought that guy was going to hurt you! He sure looked surprised!" I hope he had to change his underwear
