This is a futatokoro (matching pair of kozuka and kogai) by Nomura Masahide, known for his skillful depictions of shrimp. Masahide was a student of Nomura Masatsugu and inherited the Nomura school's tradition of precise and lively artistry. The pieces feature intricate nanako ground with detailed carvings of flounder, sayori, and spiny lobster on the kozuka, and bold compositions of goby and long-armed shrimp on the kogai, all rendered in oborogin (shakudo with silver inlay) and vibrant gold iroe.
