It's signed as "Senshu ju Sakai Kunihisa saku" and made in January, 1945. The mounting is 44 style and double match lock works fine. This katana has a suguha hamon with the nagasa of 61cm. This is a good candidate for finish polishing because there are no nick on the cutting edge and flaws except light scratches, which can be completely cleaned in finish polishing.
