In Showa 12 (1937), he entered the Nihonto Tanrenkai within the grounds of Yasukuni Shrine and studied under both swordsmiths Shimazaki Yasuoki and Yakuwa Yasutake. He was granted the character "Yasu," which is the honor of Yasukuni swordsmiths, and took the name "Yasumune." He continued making swords after the war and belonged to the All Japan Swordsmith Association. He was a highly skilled swordsmith who won the Effort Award three times at the Shinsaku Meito Ten, in addition to having many other award records. This work is a blade featuring a flamboyant choji hamon on well-tightened ko-itame hada. There are some small scratches and hike from the older polish on the blade, but there are no defects such as conspicuous kitae-ware, and the condition is generally good. The koshirae is a high-quality mounting with a kuro-ro-nuri saya featuring sendan-kizami near the koiguchi, and fuchi-kashira made of iron with Higo karakusa-mon nunome zogan. There is some feeling of use on the tsuka, but there is little damage to the inside of the koiguchi, and it is thought that the frequency of use in Iaido was low. Also, it is thought that there is no history of use in tameshigiri. Both the blade and koshirae are in good condition, and it is a recommended blade that can be used for Iaido or tameshigiri immediately after purchase. Osaki Yasumune, whose real name was Osaki Shigeharu, was born in 1915 in Yamagata Prefecture and later resided in Sumida, Tokyo. In 1937, he joined the Nihonto Tanrenkai (Japanese Sword Forging Association) at Yasukuni Shrine, where he studied under the swordsmiths Shimazaki Yasuoki and Yakuwa Yasutake. He was granted the honor of using the character “Yasu” (靖), traditionally bestowed upon Yasukuni swordsmiths, and adopted the smith name Yasumune. After World War II, he resumed sword production and became a member of the All Japan Swordsmith Association. He was a highly skilled swordsmith who received three Effort Awards and numerous other honors at the Shinsaku Meito Exhibitions. This sword features a finely forged ko-itame hada with a beautiful choji hamon. The blade has some minor scratches and light surface marks from its older polish, but there are no significant forging flaws, and its overall condition is good. The koshirae features a black gloss-lacquered saya with a sendan-kizami (thousand-step carved) design near the koiguchi. The fuchi and kashira are made of iron with Higo-style arabesque designs in nunome gold inlay, giving the mounting an elegant appearance. The tsuka shows some signs of use, but the interior of the koiguchi has very little wear, suggesting that the sword was rarely used for Iaido. It also appears that the sword has never been used for tameshigiri. Both the blade and koshirae are in good condition. This is a recommended sword, ready for immediate use in Iaido or tameshigiri after purchase. 「拵 Koshirae」 Habaki: Su-akagane-ji single-layer koshi-yujo.
