Dernière acquisition sur le net. Etrange car j'étais le seul à miser...

Voici ce que j'ai trouvé à propos de John Engström: (en anglais)
Johan Engström was born in 1846. He was one of the most successful Eskilstuna cutlers. Before setting up his factory in 1874 (Fabriksaktiebolaget Johan Engström), Johan had worked with cutlers and studied knife production in both Sheffield (Geo. Westerholm & Son) and Solingen.
At the age of 13 he travelled to learn his trade in Russia, England and Solingen. In his early years, Johan mainly produced razors and daggers.
In 1882, Johan added barrel knives to his production line. The company produced high-quality barrel knives and received international recognition at shows in Sweden, France, U.S.A., and Canada. At one time the well-known US importer Edward Zinn ordered 3000 dozen barrel knives from the Engström company.
The steel, of course, was produced from Swedish iron ore, one of the purest iron ores known. It made such good steel that many countries imported it, including England, Germany and Japan. Some german razor manufacturers even opened their own mines in Sweden. It makes a good, hard, edge-retaining steel.
Johan died in 1915 which marks the end of the Engström company. His factory ceased all operations by 1917.
In 1918 the company was renamed to Swedish Steel Forging Co.(Svenska Stalsmides Aktieb or SSA).
The Swedish steel is one of the best in Europe. Many German and French knife/razor makers used Swedish steel and learned from the Swedish Masters.
