If there is something that you need to prevent getting into your meat saw, it's rust. Once your tool develops rust, it isn't easy to have problems with the blade including breakage. Make sure that you lubricate meat saws used mostly on food with something non-toxic oils like olive oil. Avoid placing your meat saw in a leather sheath if you live in a wet environment. Instead, ensure that you wrap it with a clean cloth and keep it in a dry place like the top of a kitchen cabinet.
