In the 11th century it was documented with the ring at the handle end for the first time. Even today the crescent-shaped blade is used for the knives of fishermen or gardeners.

Today however the ring is rather used for sports e.g. in different Filipino martial arts like Pencak Silat or Philipino Kali where the knife is being rotated around the small finger.
