I see these hand made razors around from time to time and they are sometimes identified as being from the 1700's based on a picture found in Neumman's Collector's Illustrated Encyclopedia of The American Revolution. Does anyone know if this seems reasonable and whether there are fakes out there also? I imagine the span of these razors goes well into the 1800's. I have further seen very similar razors of chinese/asian origin and figure they may have made their way out here with chinese immigrantion - which really only began happening after the revolutionary war and into the 1800s.

What is this?
