Sweden has a very long tradition of making steel and tools, as described by Tekniska museet (Technical Museum) in Stockholm:
Ferrum – Swedish Iron and Steel through the Ages

KGC, founded 1950, is one of Sweden's trowel makers. Following is a translated quote from their website KGC History

Karl Gustav Cederberg, a skilled concrete worker, started the KGC's Bricklayer’s Tools 1 April 1950. KGC quickly became known for its high quality and good service, two qualities that still permeate the company.

In the 1950s there were not many shippers, thus KGC bought a Ford Anglia and delivered himself to building sites around the Stockholm area and up to Uppsala, which was then almost a day trip.

1966 sold the company to the Cederberg Hadar Gustafsson streamlined production and increased range. [In 1966 the company sold Cederberg to Hadar Gustafsson as streamlined manufacturing and extended range.] In 1979 KGC was acquired by Orwar Eriksson. On first September 2005, Patrik Wahlfridsson and Mats Engqvist took over the company.  The first catalog contained 30 products, most of them made ​​by KGC. 25 of these are still in the range and further approximately 1800 products. Many products are now, as then, developed by the KGC and we always listen to the end user to find optimum solutions to problems.
