Mokume Gane (pronounced Moe-koo-may Gah-nay) is the ancient Japanese metalworking technique developed in Japan by master swordsmiths. The name translates as "wood grain metal," referring to one of the most popular patterns created with this laminated metals technique.

In this process, layers of contrasting colored metals are fusion welded, using very high heat and pressure, into one solid block. This block is further manipulated by forging, twisting, and carving to develop more and more complex patterns.
