This is a set of kozuka and kogai (futokoromono) that once belonged to the main Tokugawa family. Both pieces are quite large and would be called an o-kozuka and an o-kogai. The o-kozuka is in the shape of a koto (the musical instrument). The back is gold and the front is a rich dark shakudo. The stings of the koto are done in gold inlay. The length of the kozuka is about 4.5 inches and the ko-gatana (blade) is 5 3/8 inches. The kogai is very unusual in that not only it is oversized also, but it is fitted with a blade that has a serrated edge and is, in fact, a saw. The kogai part of this piece is only 2 7/8 inches but the blade is 6 7/8 inches. These pieces are from the Kaga Kinko school and have been certified as Tokubetsu Hozon by the NBTHK. Also accompanying these pieces is a portion of their old box with the inscription of the relating that they were owned by the main branch of the Tokugawa family.
