The Yama Enshin is made one at a time by a father-son master silversmith team in the American Southwest who combine the design styles of the Navajo and Zuni tribes with the Japanese aesthetic of wabi-sabi. They themselves are Navajo (Dine). They utilize only the most primitive methods, all of which require a tremendous investment of time in repeated hammering and firing. They refer to this as "hammering the spirit into the tool." This enshin is thin enough perhaps to be called an enteishin. Yama in Japanese means mountain, and this is captured in the symbol on the side.
