A very nice koto era tanto that deserves to be restored in full polish and all its glory it is mumei with nice Bizen workmanship. This sword is not signed but appears to be by the Bizen group of smiths and from the muromachi period. There were many Bizen smiths working at this time and this could be one of many if attributed to this group. It is constructed in typical bizen fashion with wide tang, a classic Bizen trait. The hamon is sugu-ha in slight notare with  activity and plenty of nie with nioi. The hada looks to consist of burls of mokume blended with itame and interspersed with O-hada. Clear utsuri appears throughout the blade if looked from the correct angle..

The koshirae consist of a vermilion lacquered saya with black streaks. There are gold flowered menuki on shakudo with a matching fuchi kashira motif.. A very nice package . There is a Kodzuka which appears to be of ancient style Chinese kanji with a depiction of a fly. The koshirae are a version that fit very nice and hold tightly together. There is a mokku style iron tsuba also.. The tsuka-ito is gold with black sageo contrasting nicely with the Same. There is a copper habaki and seppa,

The blade is an excellent example of a Bizen Koto tanto and all that is left to complete this package is to  have it polished with shirasaya and then submit it to shinsa. This blade should paper very well.
