How do I get a razor blade out of a shaving razor?

Every brand offers a dozen or so different designs of razors, and there are a half dozen or more brands. Some have removable blades and some don't. So nobody has any idea what you are talking about. Figure out what brand you have. Go to images.google.com and type that in the search box. Find a picture that looks like the one you have. Post the link here. Then maybe somebody can tell you something about it.
