For a while I thought nothing was consistent with TSA. Coming out of Dayton, Ohio, I had to surrender a nice D locking snap link, told it could be used as a brass knuckle. Land at Seattle and there goes a young man with about 4 locking D snap links, snapped to his ruck, followed by another young man, obviously in the construction business, with a large claw hammer sticking out of the side pocket of his ruck, followed by another man with two Filipino fighting sticks sticking out of the pocket of his ruck. Same airport that I had a long discussion with a TSA security individual as I had pointed tweezers, until his supervisor said they were OK. John
