You shouldn't be using a knife with a chemical coating to cut food either. If a small piece of that coating makes into someone's dinner, you might be getting into some kind of serious trouble. I've seen a lot of butchering and most people used a knife that was old school 1095 with a nice dark patina. Beef has a lot of blood, and blood has a lot of salt and that is what gives you rust. If you are in a controlled environment, you might consider a dedicated butcher knife that is NSF certified. Also, consider something with a thin blade. You might want to search for dedicated butcher knives, I wouldn't be too confident in a butcher using a bushcrafting knife to cut meat I am buying at a store. Save the ESEE for your days off. Get something for your job that will perform, and that meets health codes.
