The katana of 1642
A katana signed 河内守藤原国助 (Kawachi no Kami Fujiwara Kunisuke) and dated the second month of 1642 (Kan'ei 19) is an Important Art Object (重要美術品, jūyō bijutsuhin). The NBTHK set it as a kantei piece in 2015, 2017 and 2021, and it appears, in private hands, as no. 44 in the catalogue of the exhibition of Important Art Objects at the Japanese Sword Museum (14 March to 24 May 2026). The catalogue gives it a 70.4 cm blade and the NBTHK a little over 2 shaku 4 sun 4 bu, about 74 cm. It is not recorded whether these are two measurements of the same blade or two different blades.
One of the three NBTHK issues dates it to 1643; Kan'ei 19 is 1642, as the other two say.
