Previous answer is
Hizen no Kuni Omi Daijo Fujiwara Tadahiro
肥前国近江大掾藤原忠広

Features: While most works by Tadahiro feature a suguha hamon, this piece is unique for its gonome midare hamon, making it a rare and excellent example. The Hizen smiths, particularly Omi Daijo, are renowned for their beautiful jigane and deep nioiguchi in suguha hamon. The precise arrangement of gonome midare enhances the blade’s aesthetic, producing a jigane of extraordinary beauty unique to the Hizen school. This quality was safeguarded by the Nabeshima domain, where the iron-smelting process was kept a closely guarded secret to ensure its exclusivity.
