Gendaitō by Isshinshi Kariya Naohide – Information / Opinions Welcome
I’m seeking input on a modern Japanese sword by Isshinshi Kariya Naohide (一心子 刈谷直秀).
The blade is traditionally forged and signed on the nakago:
一心子 刈谷直秀 作
(Isshinshi Kariya Naohide saku)
The tang also carries a date inscription consistent with the smith’s working period (late Shōwa to early Heisei). The sword is legally registered in Japan and includes its Torokusho.
Condition: the blade is polished with no chips or apparent fatal flaws. The nakago has natural patina and has not been over-cleaned. Koshirae are present; the tsuka fittings are somewhat loose and would likely benefit from routine adjustment or mekugi replacement.
I’ve located comparable examples by the same smith listed with established Japanese dealers (e.g., Nipponto and Tsuruginoya), which suggests this is a legitimate collectible gendaitō rather than a decorative piece.
I would appreciate any additional information regarding the smith, workmanship, or market context, and whether members feel this example is consistent with other known works by Kariya Naohide.
Photos attached. Thank you in advance for any insight.
