straight razor
A razor with a rigid steel cutting blade hinged to a case that forms a handle when the razor is open for use. Example: post #2330919
The blade is intended to be stropped and honed; a "straight razor" that uses disposable blades is technically called a shavette.
For tagging purposes this tag also includes the traditional Japanese kamisori, which consists of an open razor blade affixed to a rigid handle. Example: post #1160734
