Kanemoto Magoroku was a famous swordsmith in the Sengoku, during the Daiei Period of the Muromachi Era. The second successor to the Kanemoto School that descended from the legendary Mino School of katana, Magoroku's rise to fame would be known by his incredibly sharp blades and his synonymous trademark temperline pattern of senbonsugi, being a series of three triangular apexes with the third rising the highest like a panorama of pine trees. Out of all in the history of katana smithing, he is one of the Five Creators of Saijo O-Wazamono quality cutting katana, along with Kotetsu, Nosada, Osafune, and Sukehiro.
