I'm not sure what you're talking about. If you carry around a kitchen knife in public for no good reason, it's not a kitchen knife, it's a weapon. Likewise if you carry around a baseball bat and didn't just buy it or are on your way to a baseball game or to gift it to someone, that's a weapon too. Carrying weapons in public without a permit is illegal. If you're merely transporting the kitchen knife to a party to help your friend prepare snacks, that's clearly not a weapon even though you're in public and carrying a knife. I've done medieval reenactment in Germany and used public transit in full kit with spears and swords and everything. I've been stopped by police a few times to check that they are indeed dull and blunt and therefore can legitimately be considered sporting or theatrical equipment but that shouldn't be surprising as it effectively looked like I was "open carrying" medieval weaponry for unknown reasons. Heck, the only times I was stopped were around the time someone robbed a gas station with a sharpened katana so I can't even fault them for being careful.
