Muromachi turned sword making into an industry: the uchigatana rose with massed infantry warfare, Osafune and Seki produced bundle swords beside custom orders, and the Ming trade carried Japanese blades abroad by the tens of thousands.
This katana is unsigned (mumei) and attributed to the Shitahara school, with an old Tokubetsu Kicho certificate attributing it to Kanetomo. It features a slightly wide blade with a thick shinogi, shallow curvature, and a large kissaki, giving it a substantial feel. The blade exhibits a dark-toned jigane with prominent jihada and ji-nie activity, and a hamon of niedeki suguha and pointed gunome midare.
