Big enough for a katana ?

[Hector_A]

I recently bought my first fuchi/kashira from aoi art.

 

Are these big enough for a katana mount ?

It fits the nakago nicely but is it big enough for katana tsuka ?

 

Fuchi 3.88 cm x 2.06 cm x 1.01 cm (1.52" x 0.81" x 0.39")

Kashira 3.43 cm x 1.61 cm x 0.62 cm (1.35" x 0.63" x 0.24")

Thanks,

Hector,

 

As a general answer; yes. The common acceptance for a daito sized fuchi is 38 mm OD on the ha to mune line. However a lot depends on the tolerance between the interior of the fuchi wall and the width of the nakago where the fuchi will be in position. There must be enough space for the shitaji (wood foundation) to provide support. The wall thickness of the fuchi can greatly affect this tolerance. Thicker walls diminish the material between the interior of the fuchi and nakago, and thinner walls provide more. This, in turn, can be complicated by the samegawa (rayskin) and the relief tolerance it will require as well. Judgements that need to be determined by the maker of the handle.
