  • Shaving cooler
    Patent number: 4642893
    Abstract: A method and apparatus for improving the performance of razors. Immediately before use, the razor's edge is cooled to cause the metal of the razor to contract thermally, causing microscopic irregularities on the blade edge to recede, resulting in a sharper, smoother, blade, which is capable of giving a superior shave. In the preferred embodiment of an apparatus to cool such a razor, a coolant is sprayed on the razor's edge immediately before shaving.
