Nakago: Patina on nakago is damaged by sand paper. Remaining patina has deep blackish colour. Yasurime is katte sagari. Nakagojiri type is kiri, with traces of rough cutting (different to other sides of nakago), which would suggest that the blade is suriage.

Hamon: gunome-midare can be seen all along the ha. Detailed features are hard to notice.

The blade is covered with shallow pitting, similar to old blades which didn't rust but remained without re-polishing for a long period of time. Lines are very elegant and neatly done. All surfaces seemed to have a very smooth finish, which suggest a good polisher's work damaged over time.

Jihada: There is a tobiyaki on the shinogi line. Muneyaki can also be seen all along the mune.
Nakago: Shape and condition of nakago could suggest that it's o-suriage, shortened from katana or wakizashi.
Hamon: Mainly ko-midare in thick nie deki with gunome midare in monouchi. Few nie sake can be seen, as well as kuichigaiba closer to yokote.
