Recent style trends have included the 2-finger ring (or double ring) which may have derived from the idea of “brass knuckles” that are traditionally used for combat.

What are knuckle rings? They actually have an interesting history dating back to Ancient Rome, having evolved from the caestus, a bound hand guard made of leather and metal worn during battles and gladiator events. The use of brass knuckles has continued througout history, utilized even during the U.S. Civil War, WWI, and WWII. Knuckle rings reached the contemporary masses when they became common in hip-hop culture.
