Info on a mumei tanto

[LeonKr]

Much appreciated when I could get some information about this tanto.

 

Nagasa 29cm

Nakago 10cm

Motohabe 2,9cm

Two tiny spots of kitae ware in the Ji

 

Thanks  it advance.

Some more pictures.

Just a guess: I have seen HOSO SUGUHA in BUNGO blades.

[Stefan]

In  my humble  point  of  view the hada  points toward Ko-Uda. 

[16k]

I’d say Koto.

[Rivkin]

I'll second Uda, but will vote for 1500. There are a few period names that come up, some make more sense than others.

 

Ignorant and erroneous opinion,
