A Stunning Quality Edo Period Tanto Fuchi In Shakudo and Pure Gold. Incredible Fine Quality Chisselled Takebori Carving of Rats Around a Gold Koku Traditional Rice Bale. Signed with Kikihan

Decorated shakudō (copper/gold alloy) with a hammered ground of fine nanako (fish-roe) points and decorated with rats and an applied pure gold rice bale. Signed Sadachika with kao (the artist's personal kakihan art signature seal). A wondeful indication of his skill, one can clearly see with a 10x magnifying glass the rats individual hairs on their body.

This is probably by the master fuchgashira maker Nomoto Sadachika, although relatively little is known about him, other than he worked in the later Edo period, his skill is self evident and was obviously exemplary.

In old Japanese culture the illustration of the rat in art was not a negative connotation, but a positive one. The presence of rats symbolised a successful harvest, so their presence was a symbol of good fortune,

Nanako Ji: "fish roe ground" A surface decoration produced by forming very small raised bosses by a sharply struck punch or burin called 'nanako tagane'. Shakudo is the metal most often used, but copper and gold are quite often employed. The harder metals, shibuichi, silver and iron are rarely decorated in this way. The size of the dots vary from 0.04" to 0.008" (25 to 125 and inch) and the regularity of the work is marvelous as the dots must be spaced entirely by touch. The dots are usually arranged in straight lines or in lines parallel to the edge of the piece being decorated, but sometimes in more elaborate patterns. Used on guards since the Momoyama period although the technique existed since much earlier periods. Usually done by specialist 'nanako-shi', but sometimes done by the maker of the guard himself. The articles of sword ornamentation made by the Goto artists were practically all on shakudo grounds with nanako finish; after the emergence of the machibori artisans in the mid-Edo period and the popularity of the newly inspired kozuka, shakudo grounds with nanako finish "became the rage". Nanako finish is probably an evolution and refinement of a very old style finish (which it vaguely resembles); "millet finish", 'awa ishime', which is found on some old armorer tsuba. However, awa ishime consisted of small, round dimples punched into the surface of the ground; on the other hand, nanako is formed by striking the ground with a cup-shaped punch to raise, and project upward from the surface, small semi-hemispheric nipples. Since we find nanako finish on old yamagane grounds, it was in use as early as the Kamakura period. It is note-worthy that a nanako finish on a shakudo ground has been used since the time of the first Goto 1440 - 151 in the mitokoromono, "set of three", for use on formal or ceremonial occasions. Later, shakudo nanako became the regular finish for use by the metal artisans. (deleted repeated sentences) In applying nanako, meticulous and scrupulous care must be used in positioning and striking the "cupping tool" in order to achieve fine, regular, carefully and closely spaced, identical results, row after row. Careless, imprecise and even coarse workmanship can be detected in the nanako of some older works and on "ready made" products, but work of later years, executed with infinite and scrupulous care, are beautiful beyond belief. However, even the finest of execution of nanako finish applied to brass (shinchu) or shibuichi fails to carry the distinct air of refinement and elegance of similar work on shakudo. The very elegance of nanako workmanship reflects not only the extraordinary skills of the Japanese in the execution of minute, detailed work, but also their tremendous patience and artistic inspiration. It is said that blindness of nanako workers at thirty years of age was usual because of the microscopic and meticulous work so carefully and patiently executed. On many old tsuba, pre-dating the period of the Goto, one encounters nanako laid in horizontal or vertical rows; on subsequent work nanako was applied along curved lines conforming to the shape of the tsuba.

Shakudo {that can be used to make samurai sword mounts and fittings} is a billon of gold and copper (typically 4-10% gold, 96-90% copper) which can be treated to form an indigo/black patina resembling lacquer. Unpatinated shakudo Visually resembles bronze; the dark colour is induced by applying and heating rokusho, a special patination formula.

Shakudo was historically used in Japan to construct or decorate the finest katana fittings such as fuchi-kashira, tsuba, menuki, and kozuka; as well as other small ornaments. When it was introduced to the West in the mid-19th century, it was thought to be previously unknown outside Asia, but recent studies have suggested close similarities to certain decorative alloys used in ancient Egypt, Greece, and Rome.
