Kantei keys
- Sugata
- Blades almost always heavily shortened (ō-suriage), of about 69 to 72 cm; the Inaba-gō, 70.9 cm, with a sori of 2.0 and a width of 2.9 at the base. HD
- Jihada
- Very tight ko-itame, with fine, dense ji-nie, sometimes mokume and chikei; clear and bright, whereas in the northern smiths it is usually dark. HD
- Hamon
- Of Sagami: notare or ko-notare with gunome, plenty of nie, sunagashi, kinsuji and inazuma, wide and irregular towards the monouchi. There is also a wide suguha with chōji-ashi (Kuwana-gō) and a tight suguha, rare in him (Matsui-gō). Sesko cites him for the wide nioiguchi suguha, extremely rare in kotō. HD
- Bōshi
- Ichimai or almost ichimai, with a round or deep kaeri. HD
