This is a very nice koto tanto by the Koto Mino smith, Kanenori.  There were several generations of smiths who signed using this kanji. I believe It is a late Muromachi tanto.  

It is a quintessential muramachi tanto with a cutting edge of. The 2-character signature is completely intact.  This signature is 100% genuine. The jitetsu is a flowing itame with very fine ji-nie that create an almost utsuri like effect. 

The blade is shobu-zukuri in shape and the hamon is a peaked notare-gunome-midare with togariba.  There is a habuchi that becomes especially active in the monouchi area with areas of kinsuji and sunagashi as well as ji-nie.

There is a very active kissaki indicative of the Muromachi era when this blade was made.  The very active hamon continues into the bôshi creating a nie-kuzure effect.

Accompanying this fine sword is a beautiful style mounting with all of the components being made of horn with a black lacquered saya. The menuki are of tigers and there is a kodzuka of the many animals of the Asian zodiac.  These mountings are in very good condition. The tsuka is of a nicely aged same (rayskin) with large knodes in the upper portion. There is no wrapping of this style tsuka. The habaki is a 2-piece copper syle with a streaking rainfall design. There is a very nice bi-color sageo in the battlewrap style,
