This katana is attributed to the Enju school from Higo province, active during the late Kamakura period. It features a nagasa of 68.4cm and comes with a Tokubetsu Hozon certificate. The blade is accompanied by a black wrinkled leather koshirae with a snowflake pattern, though the koiguchi shows signs of wear from iai practice.
