Hints at a time frame based on measurements?

Hey all,

 

I'm looking at a blade that has these dimensions and am curious if this fits a certain age.

 

Iori-mune

O-suriage Mumei

Bohi through nakago

Nagasa: 65.5cm

Nakago Nagasa: 17cm

Sori: 1.3cm

Moto-Haba: 2.74cm

Saki-Haba: 1.84cm

Moto-Kasane: 5.6mm

Saki-Kasane: 4.5mm

Kissaki-Naga: 2.4cm

The curvature is in the center, chu kissaki... Either the very end of Kamakura, or between 1570 and 1640. Statistically 1,000 times more likely to be the latter.

Alright, thanks Kirill. I believe it has a mokume hada or Itame hada? I'm not experienced enough to tell the difference. Also included nakago pics if they help.

Thought I would add a couple pictures. The hamon appears to be a thin suguha (Hoso, Ito?) with several areas of humps (Komidare?). With the state of the polish, it is hard to get pics of the hamon and boshi seems obsured by damage, but here they are.

 

Would this point to a shinto school or smith?

Yep, border of Muromachi and shinto. Could be many things, like shitahara.

I'm still piecing parts and pieces together on this katana as I learn more about terms and things to look for.

 

I am seeing utsuri with roundish peaks and valleys towards the kissaki end, possibly with a dark line underneath?

 

I captured this with my ancient cell phone camera, hopefully it turns up so it can be zoomed in on to demonstrate what I'm talking about.

 

Thanks for any leads.
