Vintage 165mm funayuki fish butchery knife made for the famous Tsubaya shop in Tokyo's Kappabashi street.

This is a light deba essentially, not a deba in that the tang has a machi grind (two notches at the neck when tang goes into handle. Having a machi the blade is measured from the machi rather than from the chin, the cutting edge is 150mm making this a knife great for smaller fish. 

Knife is in good shape, it had been sharpened a little too much on the ura side so we ground that in on a kaiten mizu toishi wheel keeping the proper concave hollow grind.
