Blade at Usagiya site.  I did not realize saiha (retempered) blades could paper (unless very famous smith or significant blade)?  NOT a judgment of NBTHK, blade, or the seller.  Just found this info interesting.

That said, saiha blades can pass shinsa if they are very important examples. Typically the blade has a notation of (saiha) on the kanteisho in these cases.

yeah got the same question when I saw it.

 

Not sure if there's value in even having one, yeah sure the sword is authentic but the heart is gone. Not meaning to insult Kokaiji, he is definitely a good smith though.

I am not looking for another wak anyways.

The smith at Usagiya also rehardned blades himself that later received  NBTHK paper. 
With their words:”Sometimes NBTHK is a joke”. 
 

From my personal experience as someone that has rehardned some blades I made, I don’t think you can see if it’s original or saiha. 
 

what is a real sign of saiha anyway ?

Quoting from the site mentioned above:

"Uchida sensei then requested to test the blade with a telephone book of 1 sun 5 bu thick.

Artillery captain Omura performed the test with excellent results."

 

Seriously?

Juyo Shintogo Kunimitsu (saiha) and Tokubetsu Juyo Toshiro (saiha).

Ray, I think it was recently disproved that the Yoshimitsu was a saiha blade. It was believed to be so, but the latest interpretation is different. 
 

I have held the Yoshimitsu in my hand and it is a truly sublime blade….

Thank you Michael, I was not aware that the Toshiro had been revisited as far as saiha. 

 

Separate to that specific sword, there is an openness to award juyo and higher to a sword that is felt to be saiha (if it is otherwise deserving and an important reference example).

The thread starts with the following statement:

"I did not realize saiha (retempered) blades could paper (unless very famous smith or significant blade)..."

 

The examples of Toshiros and Shintogos proudly presented afterwards fall in the category of "famous smith or significant blade".

 

For the average collector of Nihon-To the device must be still:

Saiha is a no go.

 

Collectors of sharp militaria tools can ignore this advice, of course.
