[Safety razors] are making a comeback thanks to the close shave they provide and the extremely affordable price of the replacement blades. It basically unscrews and you can insert a razor blade. Because these razor blades are so easy to take out, safety razors are not permitted in your carry-on luggage with the blade. The blades must be stored in your checked luggage.

100 safety razor blades = $17.99 (or enough blades to last me about 4 years)
