I always see blade X was made at factory z. So what brands are made in the same place? Is Feather made in the same place as any other blade? What about Astra, and all the other brands? Any still made in the USA?
I know that all US made Personna blades are made at the American Safety Razor company in Verona Virginia (labs, meds, barbers, and the vacuum packed store 5 packs of Personna blades as well as disposable single and multi blade cart razors).
There are several blades made in St Petersburg Russia besides the Astra. I'll let others who know for sure what they all are list them but a few are the Gillette 7 o'clock yellow, green, and blue packaged blades.
Schick injector blades are made in plants in both China and Germany, while the Personna injectors, stainless GEM, Treet, GEM Blue Star, PAL and CVS brand single edge blades are made in the US of A by ASR/Personna. Feather single edge blades are made in Japan, and Dorco single edge blades are made in Korea.
