Hoof nippers look a lot like pull offs,,,used for removing shoes for the hoof. Pull offs make great tools if you reshape the working ends,,All the pull offs I have seen or used had a little ball forged onto the end of the reins. Nippers do not have the ball. Most have a little flare on the end. Nippers are indeed made from tool steel and like above would likely not survive a quench from hot. GE is one of the better made nippers and run roughly $150 a pair. If you find any of the above for a good price buy them..If they are nippers,,especially if they are GE and they have some life left in them a farrier will likely let you walk away with some profit.
