Cutting tests and corresponding gold inlay inscriptions became popular in the 17th century. Yamano Kanjuro, believed to be the first professional tester under the Tokugawa shogunate, is said to have performed tests on over 6,000 criminals. Nezu Saburobyoe Mitsumasa, who performed the cutting test on this sword, learned the cutting technique in the Yamano style. A four-volume handscroll detailing the secret technique of the Nezu cutting style are in the collection of the Seikado Bunko Art Museum, Tokyo. Nezu's cutting test inscriptions are extremely rare.
