Mystery japanese knife

[woodworkcan]

Hey KKF,

Can anyone tell me what type of knife this is and what is it designed for?
It looks like a cleaver, but it is fairly small (L=85mmW×40mm) and thin (2.5mm at heel).
It is double beveled.
Some of the Kanji apparently says Munemitsu.
I got it from an auction and was too curious to leave it to someone else ;-)

Looks like a Tatami knife, no?

I googled the tatami knives and they do match the profile. But they generally seem to be twice as large as mine.
Maybe mine would make nice doll house tatami mats?

Look like a leather-cutting knife.

The size and the profile seems to match. So it's not a food knife. Thank you.
