This razor has seen very limited use. Really limited, as I do not see any evidence of corrosion or soap build-up at the pivot pin. This is truly a collectible nude razor. The color is original and very vibrant. I would almost classify this razor as NOS (new old stock) There is a purposeful nick out of the pile side scale. It looks like it was made by making a wedge shaped cut with another cutting edge for identification. It may have been held for a customer at his local barber shop and the mark was used for knowing who it belonged to. It looks to be about a half a mm deep.
