This is a square brass Gennou for leather crafts. One side is flat and the other has a slight curve with a mirror finish.
You can flatten seams on leather goods or use it for rivets and nails with the back side.
With its square surface and pointed corner, this hammer can reach areas that other hammers cannot.
*Because the handle is made of natural wood, colors and patterns vary.
