Seek the error

Hi,

 

Where is the error?

Could it be this? :?

As my guess;

You cannot expect Kesho Yasuri on Koto blades.

hi,

 

Right Moriyama san, kesho yasurime doesn't exist in koto times.

That was going to be my second guess Moriyama san.

 

Please forgive my ignorance as I'm a complete novice but can someone explain what...

...means as there doesn't appear to be any sori at all?

Looks to me like the hamachi was moved up. As you can see, the yasurime does not extend to the rest of the nakago. The lower part certainly looks older. If you notice, the munemachi is not level with the hamachi.

 

The top of the nakago could have been redressed when the hamachi was moved. The shape looks early koto with a slight uchi-zori.

Look at the upper pics

Identifying the yasurime as not belonging with a koto tanto is correct.

 

So it's left to decide if the yasurime are wrong, or if the tanto is not koto.

 

There is something wrong with this nakago, the mekugiana is too low, and the shape below the machi is strange. The rust ends very abrubtly as well at the first yasurime with a slight sprinkle above it. The shape of the nakago ha also makes an abrupt turn here.

 

 

The workmanship in the blade looks older than Shinto to me. It has uchisori and looks polished down, both in the ji and in the sugata, which will enhance the uchisori on this kind of tanto as it is polished. It looks older than Shinto as a result.

 

So it's possible that a mumei piece had the machi moved up and the yasurime and mei added later. Or an older tanto blade was used to replace a damaged blade with an existing nakago. The mei looks no good to me at a glance, so I'd be leaning towards it being a fake for the Shinto Sukenao.

Darcy,

 

I figured the nakago looked strange, too long with a strange shape which could be explained by the hamachi being moved up.

 

Gimei didn't cross my mind until you mentioned it. Should have put more thought into it. If the blade is not koto, I thought maybe one of the shinshinto bizen sukenao. But it makes much sense as the sukenao (sukehiro kaji) is a big name.
