Why do dull razors cut you more when you’re shaving?
In: Engineering
When something is sharper it cuts smoother and easier. Imagine trying to cut something and the blade is dull, it won’t cut very well or hardly at all. Same principle applies to a razor blade. It cuts hair easier when the blade is sharp, but won’t hardly cut when it’s dull. A dull razor pulls and tugs on the facial hair which causes it to cut the skin instead of the hair.
