How do you take a blade out of a razor?

You just have to cut part of the razor that is holding the blade. Be very careful to don't cut yourself. I actually tried it, and it worked because I was aware to don't slice my fingers, or something. Good Luck

Additional answer

Depends on what sort of razor. Some razors have the handle screwed to the body and when you unscrew it the whole thing comes apart, letting you change the blade. I can't think what sort of razor requires you to cut it, as in the first answer.

Electric razors are different, each one different.
