Here is 小野一刀流 https://ja.wikipedia.org/wiki/小野派一刀流 I think maybe 信田良男 is the owner not the sword smith who made this blade.

A few more photos of this sword

For the video game, I think they did a pretty good job.

It's a video game

I just notice there are 2 Guntos in Call Of Duty: Vanguard .Mission The Numa Numa Trail.One is Type 98 without the tassel ， the other one is a Civilian mount that has wavy Hamon blade.

Legit

There is always some copper handle NCO sword on the market(2 on eBay right now), just need to find a fair price one.

助宗

This NCO is good, but the tsuba looks polished, too shinny. Scabbard color is different than the others, not sure if it is original or the factory repaint. Some people might buy it for that price, it's clean and has a low number, but the price is not for most collectors. Due to a few nice NCOs sold for the high price recently, other sellers seem to want to get the premium price as well. There are two copper NCOs for sale on the bay for a while w, list for $5K , not been sold yet. But both are not as nice as this one.

Saw this unusual type 30 bayonet, it has both Mukden and Tayogawa arsenal marks.

Yes, looks like only 行久 on the tang.

35974 VS 35479 seems they only flip the numbers a bit.

I’m sure this one can fool many people.

関住岡田兼義作

Smith name 石原兼直 Ishihara Kanenao,WW2 関市 Seki sword smith ,make sword for Army,there is no date on this sword. During WWII, more than 200 swordsmiths worked only at Seki province to supply qualified swords for their soldiers. Their names began to appear in Seki Tanrensho Booklet printed in 1939. Several smiths in this list worked as Rikugun Jumei Tosho (e.g. Nakata Kanehide) and produced both good and poor blades together. However, most of these seki smiths produced low grade Showato and should not be regarded as a Gendaito. http://www.jp-sword.com/files/seki/gendaito.html
