Family blade in gunto fittings. Opinions on period

[gustaf]

My previous gunto acquisition turned out to be a family blade in ww2 fittings. Tsuka has a Naito family mon. Tsuka was never removed from the blade since war and after much wrangling it turned out to be unsigned nagako. Nagako shows significant aging Habaki is two part gold and silver foiled. Blade geometry and lightness reminds of my Masaie blade Koto period but sugata does not support that. Hada is tight and hamon is suguta, chu-kissaki. Any thoughts and opinions are welcome from this well respected forum.

Sugata indicates Shinto, but you knew that.

I was leaning in the same direction yet wanted confirmation. Many thanks for quick response.

White metal showing through nakago patina suggests Shinshinto???

 

BaZZa.

I don't know. Yasurime are deep, crisp and well spaced on a relatively long nakago, which might be shinshinto, and yellowish brown patina would just mean exposure to elements in the last half century.

Nie foaming about the upper edge of hamon without much activity within hamon precludes koto.

Broad masaie that sort of dives back and forth into hamon is something not at all common. Sendai Kunikane is kind of automatic response here, but they usually make more or less uniform masaie throughout the blade. If transition to dense itame up towards shinogi is a photography artefact then I would personally strongly vote for Sendai Kunikane.

If there is a real transition like this, needs second thoughts.

I will go along with Bazza, with the possibility  it's Gendai.  To me, it looks like water damage to the Nakago and this is hiding some of its features.  Always hard from photos.
