Yahoo Japan seller with large number of "koto master" blades

[Gerry]

The swords being listed by this seller are rather perplexing. He's able to consistently list a large number of swords that are either "masamunes" or "sanjo munechikas", etc.

 

The thing is, the swords are actually rather nice, with lots of koto looking activity in the hamon, and sometimes even having koto jitetsu. But many of the swords are extremely healthy with ubu nakago, long nadasa, thick kasane and prominent hamachi, so it leads me to believe that they're shinshinto copies. But they're really good quality shinshinto blades. And he's able to get some pretty good prices.

 

Does anyone here think that these blades are indeed koto? Or if not, how the hell is he able to get his hands on so many high quality shinshinto blades?

 

Here's his current live listing, a "Rai Kunimitsu":

And he has excellent feedback, but suspiciously, many of the feedback for his swords have the exact same text.

 

Here are some pictures of the other swords he's recently sold...

Unpappered blades? If yes pass please.

He usually has those suspicious Hon'ami papers with the blades. Every once in a while he'll have legit looking NTHK papers. He sold a realistic looking signed fukuoka ichimonji blade last year with NTHK papers for only 1.3M yen.

Men, obtaininig recent nbthk living in Japan isn't hard. Those are not gendaito with obvious mei. Think about trouble you make trying to resell those quasi pappered blades.

It has very sharp, well defined hamon contours, as if drawn with a pencil. Really old "ashi" tend not to looks this way, this is more like Bungo.
