Solingen is a city in North Rhine-Westphalia, Germany. It is located on the northern edge of the region called Bergisches Land, south of the Ruhr area, and with a 2009 population of 161,366 is after Wuppertal the second largest city in the Bergisches Land. It is a member of the regional authority of the Rhineland. 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 towns 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.
