Japanese sword WW2 gunto signed Ujifusa yasuki steel

[Swords]

I thought this sword was interesting but like to see what others think  Also what is this Ujifusa yasuki steel used is it any better than Showa oil quenched or dose it matter 

To me Gendaito water quench is probably better ? Is this actually compared to Fukumoto Amahide,? I had to take 2 pictures of the description so it may be hard to read in order

The photo's aren't good enough to make a decent opinion.  However, it appears to be oil tempered.

Steven, will appreciate if you can post these questions under Military Swords of Japan. Thank you.

Why is for general discussion

I was looking for more info about the steel what makes it special I checked John slough and listing 3rd seat which I find strange for oil quench but I’m no expert on this

Steve,

 

@Okan suggests that as there is a designated area in the forum for blades in military outfit where most of the experts in the field gravitate around. I'm sure the post will be moved there by an admin eventually. 

 

Just a thought 

 

P.S. Slough's book has examples of medium to high grade showato also. oil quenching is a non traditional but IMHO safer way to harden hot steel that eventually transforms into a curved blade.

 

Cheers

The sword has a Sho stamp, not Gendaito but still well made by the looks of things.

[BANGBANGSAN]

It was made of 安來鋼(Hitachi Metal Ltd)，not 玉鋼，that's why it has 昭 stamp。

戦前において日立金属安来工場の前身である安来鉄鋼合資会社の伊部喜作らが、松江電灯協力のもと、東洋で初めて高速度工具鋼を電気製鋼で開発したことで近代製鋼においても更なるブランドを確立した。

現在は島根県安来市の日立金属冶金研究所で開発され同安来工場で、先端技術を駆使して造られた材料の強さが求められる刃物・金型、高性能機械等向けの工具鋼を代表とする特殊鋼すべての名称と定義されている。これらは「YSSヤスキハガネ」（YSSはYasugi Speciality Steelの略）として登録商標されている。

Before the war, Kisaku Ibe of Yasugi Steel Co., Ltd., the predecessor of Hitachi Metal Yasugi Factory, and others developed high-speed tool steel with electric steel for the first time in the East with the cooperation of Matsue Electric Light, establishing a further brand in modern steelmaking.

Currently, it is developed at the Hitachi Metallurgy Laboratory in Yasugi City, Shimane Prefecture and is defined as the names of all special steels represented by tool steels for high-performance machines, such as blades and molds that require the strength of materials manufactured using advanced technology. These are registered trademarks as "YSS Yasugi Speciality Steel" (YSS stands for Yasugi Speciality Steel).
