Would anyone know about the Gottlieb Hammesfahr Company from Solingen Germany? I bought one of their knives last night on e-bay. From what I understand it was made around 1930. and is unused??? The guy I bought it from lives in Germany. The blade has turnned a dark blue and the scales look newer but I.m no expert. I didn't pay alot for the knife so even if it dosen't live up to expections I haven't lost anything. I have bought over 80 knives on e-bay and have never had a bad experience.......Jim
