\/>\nThis blade is ranked as Jyojyo Saku among the works of Joshu Mito Ju Katsumura Tokukatsu.<\/p>\n<p>Habaki: Gold foiled single Habaki<br \/>\nBlade Length: 70.61 cm (27.80 in).<br \/>\nCurvature: 1.21 cm (0.48 in).<br \/>\nMekugi Hole: 1.<br \/>\nWidth at Base (Motohaba): 2.95 cm (1.16 in).<br \/>\nWidth at Yokote: 1.99 cm (0.78 in).<br \/>\nThickness of rim (Kasane): 0.63 cm (0.25 in).<br \/>\nSword Weight: 775 g.<\/p>\n<p>Era: August 1870 (Meiji 3)<br \/>\nShape: A katana with a relatively wide mihaba, moderate curvature, and an elongated kissaki.<br \/>\nJigane: Exceptionally well-forged ko-itame hada mixed with masame, producing a fine and refined jigane.<br \/>\nHamon: Suguha mixed with gunome, featuring numerous overlapping kinsuji.<br \/>\nThe boshi displays a midarekomi pattern, ending in a small rounded turnback with a yakitsume-like appearance.<\/p>\n<p>Features: By August 1870, Japan was approaching the period when restrictions on wearing swords would be introduced, and this must have been a matter of great concern to swordsmiths.<br \/>\nJoshu Mito Ju Katsumura Tokukatsu was undoubtedly facing similar uncertainty and may have devoted particular care to producing outstanding swords as the remaining opportunities for his craft seemed increasingly limited.<br \/>\nThis blade displays prominent masame hada in the shinogi-ji, while the exceptionally tightly forged jigane reveals a delicate, fine masame grain.<br \/>\nThe hamon is particularly impressive, with numerous layers of kinsuji creating rich and varied activity.<br \/>\nEventually, the Haitorei Edict of 1876 brought major changes to the sword-making profession, severely reducing demand for swords and interrupting production for many smiths.<br \/>\nThe craft underwent significant changes before sword production was revived in later years of the Meiji period.<\/p>\n<p>Historical Background:<br \/>\nCompletion and Lighting of Jogashima Lighthouse (August 13, 1870 \/ September 8, 1870, Gregorian Calendar)<br \/>\nJogashima Lighthouse, located at the southern tip of the Miura Peninsula, was completed and began operating as Japan&#8217;s 5th Western-style lighthouse.<br \/>\nThis was one of the important developments symbolizing the modernization of Japan&#8217;s maritime transportation.<br \/>\nEstablishment of the Engineering School and Survey Office (August 14, 1870 \/ September 9, 1870, Gregorian Calendar)<br \/>\nTo train modern engineers, the Engineering School (Kogakuryo), which later developed into the Imperial College of Engineering and eventually became part of the University of Tokyo&#8217;s Faculty of Engineering, was established under the Ministry of Public Works.<br \/>\nOn the same day, a Survey Office was established under the Ministry of Popular Affairs to conduct accurate surveys of Japan&#8217;s territory.<br \/>\nOpening of Telegraph Communication Between Osaka and Kobe (August 20, 1870 \/ September 15, 1870, Gregorian Calendar)<br \/>\nA telegraph connection was established between Osaka and Kobe, enabling communication between the 2 cities.<br \/>\nFollowing the opening of the Tokyo\u2013Yokohama telegraph line the previous year, this marked another important step in the expansion of Japan&#8217;s early telegraph network.<br \/>\nEstablishment of a Middle School in Tokyo Prefecture (August 22, 1870 \/ September 17, 1870, Gregorian Calendar)<br \/>\nOne of the first modern middle schools was established in Tokyo Prefecture, marking the beginning of a more systematic approach to modern education.<br \/>\nThese developments demonstrate the tremendous momentum behind the establishment of schools throughout Japan during this period.<\/p>\n<p>NBTHK Tokubetsu Hozon
