The nonferrous lamination process was invented by Denbei Shoami (1651-1728) when there was no distinction between armourer and a worker of precious metals in Japan. Mostly sword mountings and guards (tsuba) were created. “Mokume” in Japanese means ‘wood grain’ or ‘wood burl’ and “Game” means ‘metal’. Therefore, the term translates “wood grain metal”. Sheets of metal are welded together under pressure and heat. A block of alternating layers is created and a pattern is hammered or drilled and then rolled out. These Mokume-Gane rings are custom made and available on commission.
