This one showed up today. Only the second I have seen with the etched blade and the other was a single blade made by Robt Klaas. This one reminds me of an Anton Wingen and has a pretty neat, and very tiny tang stamp on the front which I tried to get a picture of. Kind of looks like a little man with a chef's hat with some writing and the date 1935. The rear has "Solingen" over "Made in W. Germany". Blades are all unused with a hint of age patina. Does anybody recognize the tang stamp?
