梨子地塗 Nashijinuri / Pear Ground Lacquer

What is Nashijinuri in Japanese Katana terminology?

This is a decorative technique where gold or silver powder is applied with transparent lacquer (Sukiurushi). Also written as ""Nashiji"". A technique that started in the Kamakura period, it involves applying lacquer to the surface of utensils, sprinkling pear ground powder made of gold, silver, tin, etc., and then applying transparent lacquer and polishing it to the extent that the powder does not protrude. Subsequently, there are derived items such as Tsuminashi-ji, which is sprinkled without gaps, Gyobunashi-ji, where gold foil is placed, and Enashi-ji, where Nashiji is used in the pattern.
