Hi! My name is Spas. I live in Sofia, Bulgaria. Kukeri (Bulgarian: кукери; singular: kuker, кукер) are elaborately costumed Bulgarian men, and sometimes women, who perform traditional rituals intended to scare away evil spirits and the devil at all. On front side of the knife are 3 Kukeri and on the back side is motive from the clothe which is on the foot part of the costume.
