Sayagaki(translation ):
Chikushu Ju Hidari Sadayoshi
Although the blade is O-suriage Mumei, it retains a wide body and a large kissaki, showing the typical form of the Enbun–Jōji(1356-1362) period.
The jigane is a well-forged ko-itame with tight grain, accompanied by thick ji-nie, giving it a strong and vigorous appearance. The hamon is suguha mixed with small gunome, with a thick nioikuchi, and the much nie gleaming brilliantly.
Around the monouchi, the nie becomes especially abundant, showing prominent activities such as yubashiri and nijūba, adding great interest to the blade. The boshi is pointed with hakikake, clearly displaying characteristics of the Ō-Sa school.
Its gentle hamon leads to its attribution to Sa Sadayoshi.

Features:O-Samonji (Ōsa), the founder of Samonji and the master of Sadayoshi, was the swordsmith in Kyushu. He broke away from the previous Kyushu style and created a new style in which both the blade and the jigane are bright and brilliant and Chikei and Kinsuji are mixed.

From Aoi-Art:
The beauty of the jigane is considered a hallmark of the Sa school, and this blade likewise displays a very clear, refined Jigane. Its hamon, calm yet accompanied by nie and rich activities such as nijūba, adds to the overall appeal of the piece.
