Unique historical artifact from a US WWII veteran's estate: WWII Japanese Katana Takayama Training Center Sword in Shin-Gunto mounts.

Also, se...veral interesting very small sword cuts on the mune (back edge of blade), the type made from the Japanese method of blocking another sword with the back edge of the blade.About the Sword: Takayama-To swords were developed by the Japanese Navy under the direction of Lt. Col. Takayama Masayoshi. He was the creator of Jissen Budo Takayama Ryu Batto Jutsu school of martial arts (AKA Toyama Ryu iai), and taught sword techniques at the Imperial Naval Academy during the war. These techniques were developed by Lt. Col. Takayama Masayoshi on the battlefields of China, because he claimed standard sword fighting techniques used by the Japanese army were not enough to kill an opponent with a single strike. He improved sword fighting techniques, focusing on the practical application of the sword as a weapon, particularly in the context of close-quarters battlefield and trench warfare. This sword was made to meet Lt. Col. Takayama Masayoshi's specifications for heavy combat (circa 1940).About the Steel used to make the Sword: Yasuki steel was a high grade, Japanese made alternative to Western steel, and was produced to help meet the large demand for suitable quality high carbon sword steel, while giving smiths a viable substitute for the more expensive traditional tamahagane. Today, Yasuki steel is still considered quality high-grade steel, and is used in top-of-the-line carpentry tools and cutlery (see: https://japanahome.com/journal/yasugi-steel-makes-great/).
