This was a LOT deeper than it looks and required a vet visit and 3 days box rest. He is now back in the paddock and healing well, but he won't be going on any float without boots again and even then I'm a bit leery of the idea. This is not the first time he has injured himself on the float. Last year, first weekend of November, he nicked that same fetlock. Different [less safe] float, only a superficial wound. But this time, I opened up the float to a decent pool of blood, blood smeared up the side of the float, and a very distressed horse. Even after hosing for about 20 minutes while I waited for the vet it was still bleeding. This is not a cut. It's a burn/extremely deep graze. The black is rubber off the float. The injury was discovered minutes after it occurred. Photos were taken in the process of hosing.
