I have this razor sold by the Diamond Razor Co. of Chicago. It says Diamond Razor Co. on the tang, but there is no country of origin which leads me to believe it is an American made blade. According to Goins' Encyclopedia there was a company by that name operating between 1901 and 1904. This is a 4/8 French point. Since my preference is for larger blades, I have never shaved with this one.
