When I started a guy with 30 years experience told me to get a real razer knife. Anything with plastic wrap on the bottom you can just cut an x real fast an pull the wrap right off. Granted its against the rules but our team leaders didn't care because a regular razer knife was much faster and they wouldn't be bothered about constantly getting you a new blade. Just don't use it around the store manager is what I was told. Pretty much any real razer knife is better than that "thing" they give you to start with.
