I think their is multiple things going on here. The chipping that is evident along the entire edge is what is throwing me off. What I am wondering is if the owner didn't develop rust on the blade due to the water boiling, or at least it left mineral deposits & they took a rotary device (dremel or buffer) to the razor. Looks like what a dremel would do with a wire brush attachment. As far as the missing chunks, I would say that it's a mishap of some sort like a drop: The large chips caused by hitting the counter on the way down and hitting the toe upon landing on the floor causing the crack.
