Meibun: "Tametsugu" Type: Tachi Nagasa: 2 shaku 1 sun 7 bu Sori: 4 bu Motohaba: 30.3 mm Motokasane: 7 mm Sakihaba: 20.4 mm Sakikasane: 4.7 mm Toshin: 575 grams (All measurements are approximate) Kanagawa Prefecture Board of Education. The Bicchu Province Aoe school began with Yasutsugu as the founder around the Shoan era of the Heian period, and thereafter the Aoe school produced many master swordsmiths until the late Nanbokucho period. Within this school, those from the late Heian period to the early Kamakura period are called Ko-Aoe. Representative swordsmiths of Ko-Aoe include Moritsugu, Tametsugu, Tsugutada, Sadatsugu, Yasutsugu, Kanetsugu, Tsunetsugu, Toshitsugu, Suketsugu, etc., most of whom bear the character "Tsugu" in their names. In particular, the National Treasure "Kitsunegasaki Tametsugu" is famous, and this is a miraculous blade bearing the same author's mei, which almost never appears on the market. With a thick kasane and a magnificent taihai, it is no exaggeration to say that a work of better quality than this may never be acquired again. On the hiraji, a vivid utsuri stands out beautifully; with the dynamic and powerful jigane unique to Aoe and a suguha, it features hotsure, deep konie, kinsuji, and sunagashi, making it a wonderful masterpiece and kenzen tachi that perfectly demonstrates the characteristics and highlights of the Ko-Aoe school. Rather than just being a rank above, it is peerlessly kenzen, to the point that one would not expect it to be in this condition given its era. 0 Yen (Tax included)

The Ko-Aoe school flourished in the lower basin of the Takahashi River in Bitchu Province, forging swords at the districts of Koi and Manju in a region long renowned as a source of iron. The school is traditionally held to have begun with Yasutsugu around the Joan era (1171-1175), and works produced from the end of the Heian period through approximately the mid-Kamakura period are distinguished as Ko-Aoe, with production continuing under the broader Aoe designation through the late Nanbokucho era.
