Question on jigane

[Gerry]

I just received a sword that I purchased on a whim from from Japan, and it has a rather unique hada, as shown below:

 

 

My question is, for which type of hada would this be classified? Would it be a type of yakuma or matsukawa hada? It's a mumei blade which appears to be from the  shinshinto era.

[Rivkin]

It would be along the lines of someone wanting to reproduce Matsukawa hada.

These late attempts (Ikkansai Yoshihiro school is best known for those) tend to have hamon which lacks any nie to the point it can be barely visible.

[Jacques]

I would say O Itame fairly hadadachi with masame towards the hamon 

[Gakusee]

I agree on all of the above. This to me seems enhanced with an etchant. What do we think?

[Scogg]

My first thought was acid etched

Thanks for all the responses. Here's a high res shot of the kissaki.

Ferric chloride does something similar too. It's often used on Damascus knives to highlight the different steel components. 

 

Did it come with papers?

Ok, it is quite likely Ikkansai Yoshihiro or his school. They wanted to replicate Norishige.

And just in case it's my phone camera that's making the hada look acid etched, here's a reference to use with the hada on my TBH ko-uda tachi.

No, this sword didn't come with papers, but I might bring it for shinsa at the next NTHK visit stateside.

I looked around the internet for Ikkansai Yoshihiro blades, and they definitely look similar.

 

I actually have another similar sword on the way, a hirazukuri katana with the same type of hada, and I'll share some pics when I receive it from Japan. Thanks for the suggestion!
