Very handy to enlarge a ring!

Very convenient to gradually enlarge a ring or ring: one slips the ring on the "staircase" to the desired diameter, we set the base on the wooden base that will cushion the blows. Next, we must introduce the smooth part by opening the top and then tap the top of the set with a hammer: the metal of the ring will be well dilated.
Prior to use, clean the tool that comes full of fat; I did it dry with paper towels. A cloth bag is also delivered to store the tool, once it has been cleaned.
