KATAKIRIHA-ZUKURI 片切刃造 HADAMONO 肌物 Tanto, Uda Kunimune 宇多国宗 signed

This sword is from the Muromachi period and comes with a NBTHK certificate.

Only one side of the blade is very sharp, making it extremely sharp. This is called Katakiriha-Zukuri.
This style is very rare and must have been a custom-made item.

The jigane has a very interesting pattern, Hadamono.
A dragon is painted on the side of this Yoshioka-style tsuba.
