I wear a Leatherman on duty, and occasionally a belt folder as well, I carry a small folder in a pocket or clipped on a belt every minute of every day..and when I am serious about working outside doing manly things around the property or hunting/fishing I wear a small fixed blade (SOG Seal Pup Elite usually).
I don't even consider the legal aspect, every single person I know is either a tradesman, police officer, firefighter, recreational shooter, hunter, etc. and it's nearly impossible that any man woman or child on the planet can't come up with a legitimate reason to have a sharp object to make things that are one piece into 2 or more pieces.
The only reason I can see someone saying they never need a knife is because someone else in the room lends them one.
