This example shows Mistumasa's skill at katakiribori. Rinsendo Mitsumasa is a highly regarded maker. He is ranked at the Yuko level (優工) by Wakayama. The theme is children playing and dancing to music. The design has great movement. The skillful use of negative space and figure size create depth in the scene. Mitsumasa was born in 1721 and lived in Kunitomo. His civilian name was Tsuji Genzaemon. He later changed his first name to Tanji. His brother was active as a gunsmith and it is assumed that this was also Mitsumasa's profession until he switched to making tosogu. Mitsumasa studied in Edo under the 2nd generation Yokoya Soyo and also studied in Nara. A trait of Mitsumasa was to inlay his craftsman name. In the case of this work, he inlayed his kao in gold.

The Hikone school of sword fittings -- known as Hikone-bori -- was established at Nakayabu in Hikone, Omi Province, by Mogarashi Nyudo Soten, who settled there after leaving Kyoto and entered the service of the Kawakita family, hereditary vassals of the Hikone domain. One source records that Soten initially trained under the Goto family, citing the Kinko Soran for the existence of works signed "made by Kitagawa Hidenori, a disciple of the Goto," before developing the distinctive carving manner that would define his lineage. The school's connection to the broader Mino-bori tradition is also recognized. There were reportedly two generations working under Soten's name, with the first born in Joo 1 (1652) and active from the early through mid-Edo period. From his workshop emerged a circle of accomplished students, chief among them Nomura Kanenori and Munenori, who carried the Hikone-bori manner forward and established it as one of the most distinctive regional styles in the kinko tradition. The technical hallmark of Hikone-bori is sukidashi takabori -- richly modeled high-relief carving executed on generously proportioned iron plates, further enlivened through zogan iroe employing gold, silver, shakudo, and suaka. The NBTHK notes that even among the gold applications, "multiple types of gold are used," producing expansive pictorial fields of considerable chromatic variety.
Subjects encompass warriors, Daoist immortals, elder sages at elegant gatherings, and flowers-and-birds compositions, rendered across the entirety of both surfaces of the guard. The school's masters also demonstrated facility in shakudo work, including nanako-ji plates with high-relief compositions displaying a pronounced Goto-like flavor, as well as nikubori ji-sukashi and polychrome mitokoromono sets. What unifies the school's output is the synthesis of imposing compositional scale with refined polychrome technique. " Munenori's contribution is recognized for its assured command of shakudo nanako-ji ground preparation and boldly modeled takabori, enriched with polychrome iroe employing multiple varieties of gold across both faces -- a sumptuous, animated effect characteristic of the mature Hikone style. The Hikone school's significance within the broader kinko tradition rests on its creation of a distinctively pictorial approach to sword-fitting decoration that stands apart from both the restrained elegance of the Goto mainline and the narrative density of the Yokoya school. The NBTHK's evaluative language converges on a single defining quality: the school's ability to fill expansive iron and shakudo surfaces with ambitious narrative compositions while maintaining compositional coherence and chromatic refinement. " That Soten's overwhelming fame led later makers to adopt his signature on subsequent Hikone-carved works testifies to the enduring authority of the school's founding aesthetic, while the surviving origami documentation -- including one dated Kanbun 5 (1665) from Goto Mitsutomo -- provides valuable evidence for understanding workshop practices and the collaborative production that sustained the Hikone tradition across the early and mid-Edo period.
