The Shovelhead is a funny razor: the cap is hinged in the front rather than the back, so it opens opposite from other single edge razors. And that cap does bear a resemblance to the business end of a shovel. Many find it fearsomely aggressive, while others love it. This one is user grade: functionally just fine but definitely showing its age. The "PAT APP'D FOR" stamp indicates that it's an early example, probably made between 1919 and 1924.
