katana-sized kabutowari???

[fearn]

I'm not sure whether posting the picture from the book here constitutes "fair use," but his kabutowari is straight bladed, about the length of the katana in the picture, with a chisel tip, a hook on the back (as in the conventional kabutowari) and a simple grip. I've never seen anything like it elsewhere, which is why I posted the question.

Best,
