So many razors seem to be called Solingen this and Solingen that.

I get that its a city in Germany with a long history of making bladed weapons.

This is from the wikipedia page about the city:
Solingen is called the "City of Blades", since it has long been renowned for the manufacturing of fine swords, knives, scissors and razors made by famous firms such as Dreiturm, DOVO Solingen, Wüsthof, J. A. Henckels, Böker, Klauberg, Eickhorn-Solingen, and numerous other manufacturers.
In Medieval times, the swordsmiths of Solingen coined the town's image, which is preserved to this date. In the latter part of the 17th century, a group of swordsmiths from Solingen broke their guild oaths by taking their sword-making secrets with them to Shotley Bridge, County Durham in England.

But why are so many razors still made there today? Blade manufacture is a world wide business, and metals are just as good everywhere around the world. So it is mostly a fashionable selling point to claim a blade is "Solingen"? Or are the majority of them made there and re-sold as blanks to other companies?

Just curious.

Thanks.
