FWIW, I would never be able to get any knife into a Courthouse in New York. Yesterday, I got my P-51 into the Supreme Court of the State of New York, Bronx County. Sparky Lyle, IIRC, wrote a book The Bronx Zoo about the 1970s Yankees. That's nothing compared with the Courthouse up the hill from the stadium.

I put my key chain with my P-51 and little flashlight into the plastic bin and handed it to the court officer acting as security guard. he picked up my key chain, and looked it, including the P-51 over, and gave it all back to me and let me proceed on my way to search for the office I wanted. He was not Mr. Friendly. When I asked for the office's location, he said "I got no idea."

When I cannot carry any knife, my P-51 lets me have something.
