Among Navajo the silversmith's craft is practiced as a household enterprise. In many hogan - huts - stood an anvil and a table for the silversmith's tools. Several family members were often involved in this work. Generally speaking, the father taught his skills to his son and the uncle to his nephew. <Br>The growing tourism enhanced the demand and after World War Two workshops were established in which several hand-craftsmen made silver jewellery for the tourist market. Semi-factory production also existed: machines were used for stamping and punching the pieces, after which they were finished by hand. The silversmiths produced new items and decorations: tobacco and cigarette boxes, combs and letter openers. Because rich clients and collectors asked for high-quality products and therefore silverwork by hand - traditional and modern - also continued. Handwork was also stimulated by the introduction of annual prizes for the most beautiful jewellery.
