I present to you a Habaki in perforated and engraved copper for wakizashi.

Hello

The shinogi extends into the nakago Jiri following the general corbure of the blade.

The blade is surage with the point of curvature of the Koshi zori 9 cm from the Munemachi. So it originally had a larger sori of around 20mm.

I think the original Menuki Ana has been lost; but that's just a feeling. Otherwise, I was wrong, there are only two Menuki Ana on the current Nakago.

Best regard

Hello, I would like to introduce you to my surage katana with a takashi shinogi; this results in a section that looks a bit like a rhombus.

I have read that the important shinogi were characteristic of the Yamato style, and associated schools (Uda, Mihara, Nio, Kongobei, Naminohira). Some blacksmiths are also known to have forged their blades with wide shinogi.

However, the blade is Saki-zori with an 11mm sori which should (when it was ubu) be around 20mm taking into account the shinogi which extends into the nakago which is rather typical of Bizen.

Of course, it is probably impossible to determine a school without holding the blade in hand. My question is more general: Is it fair to think that because of the broad shinogi (shinogi takashi) the blade is Koto ?

Could this blade in particular be early Muromachi or even older ?

Is the temper line Sugu ?

total length 79cm

with a sori: 16 mm

Nagasa: 62 cm

With a sori: 11 mm

Moto-kasane: A = 0.60 cm

                         B = 0.49 cm

Saki-gasane: A = 0.38 cm

                        B = 0.28 cm

Moto Haba 29mm 

Saki Haba 20.8mm

Kissagi: 33mm shu kissaki

Hada: Masame / itamé ?

Possible school Yamato ?

Saki-zori weak because she is surage

blade weight 515 gr

Mekugi: 3

Thanks for your help

Hello,

I'm not a expert but I see in the down center a ORIGAMI (折紙) SIGNATURES like page 66 of the NIHONTŌ COMPENDIUM © 2015 Markus Sesko
