To perform
yubitsume, one lays down a small clean cloth and lays the hand onto the cloth facing down. Using an extremely sharp knife, or
tantō, the person cuts off the portion of his left little finger above the top knuckle on the finger or the tip of the finger. He then wraps the severed portion in the cloth and submits the "package" very graciously to his
oyabun ("godfather" or boss), who is also referred to as a
kumicho (patriarch/head of the family) – or to whomever this gesture of atonement is made, if it is not to his own boss. If more offenses are committed, then the person moves on to the next joint of the finger to perform
yubitsume. More infractions could mean removing portions of the right little finger when no more joints of the left finger remain. In some cases, a person expelled from a
yakuza gang might be required to perform the
yubitsume ritual. The finger of the yakuza directly responsible for an offense is called an
shinu yubi, "dead finger", while the finger of the yakuza that is directly in charge of him is called a
iki yubi, "living finger". ==References==
