I agree with wvtools. Looks more like a cotter pin tool than farrier's hoof pick.
Hoof picks have more of an angle to working ends, and typically one end only. They are angled, usually about 90 degrees, for leverage, because the muck and stuff gets packed in real tight. Imagine holding the hoof upside down while trying to remove all the hard packed junk in and around the frog, and the shoe. This tool just wouldn't work well.
I've spent some considerable time with farriers in the past as a helper, and for the life of me can't figure how it would aid in trimming operations. That is accomplished with a hooked hoof knife, parers, and nippers.
Just my .02, as I married into a horse family, and have been around them for the last 18 years or so. Just my experience.
