Quote:Now engineers at MIT have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair—a material that is 50 times softer than the blade itself. They found that hair shaving deforms a blade in a way that is more complex than simply wearing down the edge over time. In fact, a single strand of hair can cause the edge of a blade to chip under specific conditions. Once an initial crack forms, the blade is vulnerable to further chipping. As more cracks accumulate around the initial chip, the razor's edge can quickly dull.


A decent read and some interesting videos of blades cutting hair taken through an scanning electron microscope.

If the diamond stylus hurt LPs in college I'd not be able to play Rod Stewart's live album in Anaheim over 1000x!
