How to cut the wax from this cheese?
I usually cut the wheel of cheese, wax and all. So cut a quarter or a half off, depending on how much you want to eat. Then, you can simply peel the wax off. Clean the knife of wax before using it again to cut cheese you'll be eating.

EDIT:

Another solution (upon a quick Googling to search for an answer to @Joe's issue in the comment) could be to use a vegetable peeler to peel layers of problematic wax off until getting to cheese goodness: http://nomenu.com/?p=43877
