The blade has been a conundrum to me. I bought it in gun to mounts. Pretty bad polish but the hada was visible. Sent it to be polished, new habaki and shirasaya made. The Nagasaki is just under 24", suriage or o suriage. 3 mekugi Ana. Maru mune. It had an unreadable mei, something Mitsu, which the polisher said was bad and he removed it. He suggested it go to shinsa and that was my plan, but after I got it back from him, other things kept happening to prevent me spending the money for shinsa, so I've just been holding on to it. One on side the Harmon is very gunome and on the other more suguha, but the activity in question appears on both sides.
