This Kanetsuna belongs to Jyo-Saku ranking.
The blade was polished by good polisher.

Special feature : The founder of Kanetsune started from Nanbokucyo period and continued to late Muromachi period.
I think the blade is late Muromachi period because the blade is rather wide and sakizori style Tanto.
(shinogi line is the style of going up)
The jigane is quite well nice Jigane with shirake utsuri style healthy blade.
Generally Sue seki style sword or Tanto are not good reputation.
It means 70% of Mino school swords are not good reputation because the blade has some Kizu and dark hamon.
But 30% of swords are well Jignae and Hamon.
We can say this sword is nice fantastic Jigane and also temper line which is typical high grade Mino school Tanto.
