It is regarded as a sword guard created by Rakuju (1817~1884), the 3rd of the Kamiyoshi school, based on the style of the work. Rakuju was a skillful craftsman, being called the second-coming of Hayashi Matashichi. He was good at inlaying texture patterns and creating open work design by learning the style of Matashichi’s work. This round-shaped iron piece has an open-work design of pine-like shape. It is sprinkled with gold inlay dead tree pattern on the flat area. The abstract inlay pattern is reminiscent of Matashichi.
