There is one improvement to be made with that tool. Apply a section of leather or neoprene foam to the area that will contact the fork crown, the bottom of the working area. Insures no nicks on the fork when the race breaks free.

Now many years ago I bought a Full Campagnolo tool case, I was spoiled when working for shops back in the day. After I moved and began working for another shop, it took a bit of lobbying to convince the owner to buy his. Afterward the shop's reputation went up, and I am sure the tools paid for themselves in short order. The one non Camapgnolo tool at the time that was really useful was the Shimano derailleur tab alignment tool set, almost necessary to get early SIS working well. What made me laugh was one of the key components of that tool was designed to work with a Campagnolo hub, they called it C brand in the tech notes.
