The effect of the blade is even from the base to the tip, and "Nioi-kuchi (small particles of Martensite) is tight and turns into the blade tip like it's disappearing quickly" as the greatest characteristic, and tightening Nioi-kuchi and having an effect of the blade feature are typical techniques of the Koto (Old Swords) period, and Kyoshu, a samurai connoisseur highly praised its fine steel for surpassing Heian and Kamakura (they are supposed to be second-class craftsmen), and it is even said that it all comes down to Kanesada; Contrary to the "wide change" seen in Magoroku Kanemoto, it has a "serene" work style; most of the works with the inscription of Nosada have fancy blade patterns which amateurs like; the inscription is done by himself, without an inscriber, which makes the inscription "deep."
「刃中の働きは元から切っ先までむらなく”匂い口が締まってサーッと消え入りそうに刃先に向かう”のが最大の特徴であり、匂い口を締て刃中を働かせていいることなど古刀期ならではの技量であり、地鉄の良さが平安・鎌倉（”二流工”の意味）をも凌ぐと武家目利の興趣は絶賛しており、兼定に始まって兼定に終わるとさえ云われている、孫六兼元のような”変化の激しさ”とは対照的に”静寂”な作風である、之定銘の作は素人受けする派手な刃紋が多い、銘は自身銘であり、銘切師には一切切らせておらず”奥義”のある銘振りである。
