Kanenaga Razor. This is made in Ono city of Hyogo pref. Name is "Kanenaga". It is made from blue #2 steel and comes with a sting ray wrapped handle. The razor measures 53mm on the edge and 155mm overall. It comes in a nice magnolia wood box pictured. These razors are hand made in Japan and somewhat rare. There's no data on hrc that I can find yet.
