Greetings.
I'm seeking higher opinions on two items. Although first introduced to Nihonto in my youth, I've always been more of a Kendo/Kenjutsu/Batto practitioner rather than a collector or Nihonto enthusiast. As such, more informed opinions would be most appreciated.
First of all, regarding the NTHK (NPO) origami attached below, in short, I find it very unusual and almost unbelievable that my mumei wakizashi was recently attributed specifically to Yosozaemon Sukesada, Daiei era. How much weight does this NTHK (NPO) origami hold relative to NBTHK or NTHK (Yoshikawa)? PM responses are okay.
Secondly, I have a Koto sankaku/omi yari signed é•·å‰ (Chokichi or Nagayoshi), supposedly a Yamashiro blade, ayasugi-hada, suguha hamon, uncut. If anyone with expertise would be so kind as to make an informed estimate of which Chokichi/Nagayoshi this would most likely be attributed to (as well as era), I'd love to hear your thoughts. PM's are fine again if you don't want to post in the open.
It was probably foolish of me, but not wanting another yari (already having this one), I recently passed up on a Kawai Hisayuki chidori jumonji yari (Keio 2) from a friend's private collection and instead helped facilitate its sale to a 3rd party Kendo sensei friend.
I apologize in advance for any errors with this post, as it's my first time using this medium. I hope the photos display properly.
Thank you in advance for any assistance provided.
