You forgot one - the inspector, who makes sure there are no hairs in or on the final product. When prep is done right, it's a boring job, but we always find 2 or 3 hairs we need to remove just before packaging.
And as others have said - you only "need" 2 knives. Use the leftover money for a good vacuum sealing machine. That is an incredible tool. No more freezer burn, and you can easily quick-thaw the meat by dumping the bag in a bowl of cold water. A lot of experts will tell you you are better off cooking steaks from frozen, but when vacuum sealed and thawed in cold water, I find very little difference between fresh and frozen. ANd as another poster has said, you can save a crapload of money buying whole sirloins and pork loins, then cutting them up and packaging.
