A few years ago I started working at a brand new production facility. Rules and regs were not yet put into place so a few of the employees carried small knives to cut plastic strap, stretch wrap, cardboard, or whatever. I loved it because it gave me a chance to exercise my collection.
There was one jerkoff employee that ruined it for everyone. He was a 30 something male and threatened a 50 something female because he thought she was talking smack about him. He took his cheap Pakistani liner lock and made a throat slash gesture towards her. She reported it and suddenly personal knives were not allowed on the production floor.
