Karl, I've never work in a "pack", meat processing place. Just north of us they have a Tyson pork plant.
From going to a few garage sales, it looks like Tyson uses Victorinox knives, and they grind them often. When the knives get thin enough they must follow the help home.
Going on a brief sidetrack here - when I was at Wilson's, if someone had occasion to pass through the "wienie room", they would appropriate a package or two in the pouch of their hooded sweatshirt to be heated in the knife sterilizers.
