(We divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku).
\nThis blade is ranked as Jyojyo Saku among the works of Satsuma no Kuni Hoki no Kami Ason Masayuki.
\nHabaki: Double-layer gold-covered habaki.
\nBlade Length: 77.4 cm (30.47 in).
\nCurvature: 2.0 cm (0.79 in).
\nMekugi Hole: 1.
\nWidth at Base (Motohaba): 3.24 cm (1.28 in).
\nWidth at Yokote: 2.18 cm (0.86 in).
\nThickness of rim (Kasane): 0.75 cm (0.30 in).
\nSword Weight: 840 g.
\nEra: Edo period, dated Kyowa 1 (1801).
\nShape: A robust, long blade measuring 77.4 cm (30.47 in), with deep curvature and an elongated kissaki, giving it an excellent overall form.
\nJigane: The grain flows in a masame pattern, producing a dark-toned steel surface.
\nThe steel is exceptionally well forged.
\nHamon: Gunome-midare mixed with ko-gunome.
\nThe boshi continues into an irregular midare pattern.<\/p>\n

Features: Masayuki was a Kyushu swordsmith whose workmanship closely resembles that of Motohira.
\nThis blade also displays the characteristic hidden chisel mark (kakushi-tagane).
\nIf the file mark on the tang is positioned slightly off the centerline, it is considered evidence of an authentic signature.
\nConversely, if the line runs exactly down the center of the tang, the signature should be regarded as a forgery.<\/p>\n

Aoi Art\u2019s Comment: This example by Masayuki is particularly rare because it is signed \u201cSatsuma no Kuni,\u201d followed by \u201cHoki no Kami Ason Masayuki.\u201d
\nI have never encountered this exact form of signature before, making it an exceptionally uncommon work.
\nIt is, of course, authentic.
\nThis is a blade I can highly recommend.
\nIt is notably long, with deeper-than-usual curvature and an elongated kissaki.<\/p>\n

NBTHK Tokubetsu Hozon Token.<\/p>\n
