Heller Bros. Farrier tool (updated)

I've always avoided any contact with horses, in our family the boys went for motorcycles, the girls- horses, so I can't say exactly what this tool is for- at a guess its a clinching hammer? Seems handmade or at least crudely-made for a production process. We've covered the Heller Bros. Toolmakers in a previous post.

Update; A reader has sent in this information, "The tool in your post is called a clinch cutter. It is used to cut the nail clinches when removing a horse shoe. Looks to be hand forged."
