Artisan Ko-Aoe Suketsugu (助次)
Era Mid-Kamakura period
Explanation The Aoe group of Bitchū Province is traditionally said to have begun with Yasutsugu around the Jōan era, and thereafter, down to the late Nanbokuchō period, produced many eminent smiths. Within this group, works that do not descend later than roughly the mid-Kamakura period are especially referred to as Ko-Aoe.
As for the style of Ko-Aoe: in the forging, mokume tends to be conspicuous and the grain often stands slightly, producing what is termed a crepe-like (chirimen) texture; many examples also show mixed jihada irregularities. The tempering includes gentle suguha-toned patterns as well as patterns mixed with small undulations; in general the nie is prominent, and overall—compared with Yamashiro works of the same period—Ko-Aoe conveys a somewhat more subdued, austere taste. Representative Ko-Aoe smiths include Moritsugu, Tametsugu, Tsugie, Tsugutada, Sadatsugu, Yasutsugu, Kanetsugu, Tsunetsugu, Toshitsugu, and this Suketsugu. Many of them share the character “tsugu” (次) as a common element in their names. Moreover, many cut the signature on the ura, and their file marks tend to be ō-suji—points that differ, for example, from Ko-Bizen.
This tachi shows a kitae of ko-itame mixed with mokume, finely standing to present the so-called crepe-like texture; and its hamon is fundamentally suguha with small gunome mixed in. In addition, features such as the original ō-sujikai file marks and the placement of the signature on the ura clearly display Ko-Aoe characteristics throughout. The rather slender sugata is well complemented by the archaic hamon—nioi-dominant with ko-nie—which stands out attractively. The ji and ha possess urumi (a moist, soft luster) and a high sense of dignity, and both ji and ha are kenzen (sound and well-preserved).
