I can't tell you much about your razor's past, but I can see into its future. And my crystal ball says that your are going to have quite a bit of work to get that ol' boy into shaving condition. Once you get that rather large chip removed, your new bevel will have to be set smack in the middle of all that rust. I hope that rust is only on the surface and not pitted too deeply. My crystal ball is now fogging over and I must rest. . . . .

Good Luck!
