The one on the bottom with canvas cover.

Agree with John, it looks like 造兵刀 to me.

本 or 夲？

Thomas Why use 松 for 長野縣？Maybe because the well known 松本城？

Thomas Thanks for the links,I guess the last one just like some remove the sho or Seki mark so can get the blade 鑑定書。

I‘m sorry Thomas, I don't remember where I got it.I will let you know If I ever see it again...

Yes,it looks like a iron guard Type 95.

Fingers

Tang don't look Chinese fake.

Here is one that has very similar Kabutogane&Tsuba, but without Menuki.

@Bruce Pennington Star stamp Kanehisa in Type 98 fit 濃州住兼久 昭和十九年三月

Still not sure what is that mark means.Could be like AlphaRaider said ,some kind of Buddhist character ,like 恒(永恒 Eternal，恒心 Perseverance) or 悟(领悟 Comprehend) or Korean character 알（ 알다 Understand)?

You nailed it,Thomas

Bruce Here you go.

Bruce Another 造兵刀 with number K781 on the Tang , Seppa.

村田刀&造兵刀 are two different things. http://ohmura-study.net/911.html Maruta to 造兵廠刀 (軍人会館呼称) 一般俗称は「造兵刀」。九一式下士用刀 (昭和6～7年) が始まりで、この内、将校に販売されたものを指す。 後の九五式刀身も包含する。「造兵廠で作られた刀身」という意味の通称である。便宜上この市販品を前期造兵刀としておく。 「陸軍刀剣鋼 (C1.0%-1.1%) を使用し、圧延ロール及び機械ハンマー等により鍛造成型。 寸法、重量は、官給下士官用制式造兵刀より稍軽量で細身。 油焼入したものを乾燥研磨による機械仕上げをした。刃文無し」 (尾藤少佐回想記より) 。 原型は三十二年式下士官刀。本来下士官刀だが、将校用刀身の不足、鍛錬刀の非生産性を補う為、満州～上海事変が勃発した 昭和6～7年頃から将校に販売された

Yes,It's a Japanese sword business that introduces/explains the sword regulations/register in Japan.

Like Thomas and John said ,It should be a normal 造兵刀， nothing too special, these swords showed up all the time. @Bruce Pennington Major Bitō's (Nagoya Army Arsenal Seki Part Factory manager) account of recollection is as follows. "The shape and the size applied to the forging sword correspondingly in general. A blade uses army sword steel (C1.0%-1.1%). Fire structure one-piece-no-forging fabrication was carried out. And curvature was attached and a tempering in oil (840 degree Centigrade) and tempering were returned (530 degrees). According to the forging sword, it polished good. Although it does not break for a tempering in oil, there is no tempered line(Hamon). Sword material is also army sword steel and cannot hold a decisive difference with Type 95 only by this explanation other than a polish.
