兼在(かねあり)は室町期の美濃刀工。『日本刀銘鑑』には関善定門の永享頃の室屋左衛門五郎、長禄頃の兼在、延徳頃の室屋右衛門五郎、天正頃の室屋右衛門五郎が載せられ、また濃刕関住人兼在銘の文亀三年二月日紀の直刃の刀(六十六回重要刀剣)があり、戦国期最大の業物作者関孫六兼元と同時期に活躍した兼在も実在していることがわかる。 表題の短刀は孫六兼元にもある「濃州赤坂住」の住居銘があり、製作も孫六と同時期の大永頃とみられ、身幅充分で重ね薄く、僅かに内反りが付き、表裏に腰樋が掻かれて凛とした造り込み。地鉄は板目に杢、流れごころの肌を交えて肌目が鮮明に現れ、関映りが立つ温潤味のある味わい深い肌合い。胸を締め付けるような細直刃の刃文は、白雪のような小沸で刃縁が締まってきっぱりと冴え、刃中も澄んで水色を呈する。帽子は端正な小丸。「濃州赤坂住」の住居銘は孫六兼元の大永八年八月日紀の刀の住居銘に酷似し、「兼」「作」の銘形も近似。兼元は関から美濃赤坂(不破郡赤坂 現大垣市)に移住し、同地産の極上の赤鉄鉱で作刀と伝える(注)。兼在は恐らく孫六と有縁で、本作も赤坂の極上の赤鉄鉱で精鍛されたのであろう、出来が抜群に優れている。家紋図目貫と秋草図の古寂な小柄の付された茶潤塗鞘の上品な拵に収められている。 注...赤坂には東大寺領大井荘があり、美濃千手院派の本拠。孫六兼元と赤坂については、鈴木卓夫先生『室町期美濃刀工の研究』に詳しい。

Seki (関), in Mino Province, grew from two roots set down in the Nanbokuchō period and rose to become the great center of mass sword production in the late medieval age. The published sources trace the wellspring of Mino swordmaking to Kinju (whose name the commentary also reads Kaneshige), counted since antiquity among the Masamune Jittetsu, the ten disciples of Sōshū Masamune, and to Kaneuji of the Shizu line; the Kokon Meizukushi records Kinju as a native of Tsuruga in Echizen who "crossed over to Seki and resided there," carrying the Sōshū-den manner east. Beneath that Sagami inheritance lay a Yamato foundation, legible in the Tegai descent of the Seki Zensada line through Kaneyoshi, so that the Mino-den the Seki workshops forged stands as a fusion of Yamato grain and Sōshū activity in nie. From this Nanbokuchō founding the name multiplied across the Muromachi period into Sue-Seki, the last and largest body of the tradition; its representative masters at the close of the old-sword age were Magoroku Kanemoto, famed for the sanbonsugi, and Izumi no Kami Kanesada, the smith called Nosada, while the Kanefusa, Ujifusa and Daidō hands worked beside them and the move of Wakasa no Kami Ujifusa to Kiyosu carried the Mino body to the threshold of Owari shintō. A common Mino vocabulary binds the Seki body, however widely its members range. The forging is an itame that stands and runs to masame, often mixed with mokume and nagare, over which rises the cool whitish shirake-utsuri of Mino steel rather than the bright midare-utsuri of Bizen; this pale, standing jigane is the constant tell the judges read first, present alike on Kinju's Nanbokuchō katana, Kaneyoshi's Ōei tachi and Nosada's late-Muromachi blades. Over it the smiths temper gunome into which the pointed togariba of Mino enters, with ko-nie clinging to a tight nioiguchi, ashi and yō, and sunagashi streaming through; the bōshi answers in midare-komi turning to a pointed or jizō-cast ko-maru swept with hakikake. From this shared grammar the individual hands diverge.
Kanemoto fixed the regular three-cedar sanbonsugi of pointed teeth; Kanefusa devised the rounded-head, constricted-waist "Kanefusa midare"; Kinju and the early founders held a calmer, rounder gunome away from the restless Shizu line, their work laid with thicker ji-nie and dry, standing grain. The late masters carried the manner to a higher finish: Nosada wove togariba among rounder forms for a broader temper than Kanemoto's one-sided file, and turned at times to a slender Rai-styled suguha with a hidden gunome; Kaneyoshi held instead to a cool ito-suguha, the disciplined Yamato face of late Seki, lightly broken with ko-gunome. A collector seeks Seki because it is the connoisseur's ground for reading Mino-den across a vast body of signed and attributed work. The kantei runs through the jigane first: the standing, masame-leaning itame and the whitish shirake separate a Seki blade from Bizen and Yamashiro, after which the pointed togariba, the dry nie, and the pointed or jizō bōshi confirm the province; the discriminations the judges draw, Kinju held apart from Shizu by his rounder gunome, Nosada parted from Kanemoto by his breadth, give the eye its anchors. Within the school the standing of the best members is settled: Magoroku Kanemoto for the sanbonsugi, Nosada whom the swordbooks call simply "an excellent master" and the most accomplished of the several Kanesada hands, and the early Kinju as a rare and precious founding name, his record running through the Jūyō tier with the signed pieces few and the long blades attributed den. Signature works carry real provenance: a Kinju tantō presented to the Tokugawa shogunal house in 1679, a Nosada katana borne by a chief retainer of the Kii Tokugawa and a tachi forged for the father of Takeda Shingen, a Kaneyoshi tachi transmitted in the Chikuzen Kuroda family. Beyond connoisseurship, Seki's blades earned a battlefield reputation for cutting; the full hiraniku and stout build of the Sue-Seki katana, made to sever, set the wazamono standing that made Mino the working sword of its age.
