DUBL DUCK "Blue Surgical Steel"
Hard to find specimen. Dubl Duck also made straight razors which are highly collectible & valuable. Not many of their DE blades survived so they are quite scarce especially in this high grade condition.
Blue blade also has two ducks etched on it. Slottage indicates late 1920s - 1930s
