Appraisal Quiz : #405

Previous answer is

Special feature : Muramasa is a swordsmith at Ise Kuwana province. The blades forged by Muramasa are very famous as  ‘Yoto Muramasa’ (as a meaning of ‘cursed sword Muramasa’).
Lore of Yoto Murasama desends on the episode of Tokugawa Ieyasu, the first Shogun on Edo shogunate.
When the grand father of Ieyasu, Hirotada has been killed, the assassin used the Katana forged by Muramasa. And when the father of Ieyasu, Nobuyasu was ordered to Seppuku, the sword used for Kaishaku was also Muramasa.
Ieyasu himself has injured on battle of Sekigahara by Muramasa Yari. Ieyasu feared Muramasa so Tokugawa Shogunate has prohibited for holding Muramasa.
So many Daimyo removed the signature of Muramasa from Nakago like this Tanto.
But some Daimyo Opponents to Tokugawa Syogunate rather collected Muramasa secretly.
The students of the Muramasa are Masashige, Masazane and so on.
I think The Hamon of the Muramasa is very big different from other swordsmiths.
Generally Hamon of Muramasa are square shape Gunome-midare symmetry on both sides of the blade. This is typical characteristics of Sengo school.

1 : Hamon are same shape on both sides of the blade.
2 : Blade is Mitsumune style.
3 : Mekugiana is larger than Tanto forged by any other swordsmiths.
4 : Please take a look to Nakago shape carefully. This Tanago-Hara style is characteristic of Muramasa Tanto.
