Indonesian Cockspurs, 19th-early 20th century.
Cockfighting has been integral to the cultures of Bali and Lombok and the practice was only banned on Bali as late as 1981. It was a sport pursued by men and was tied in with religious rituals as well as gambling. Cock spurs (taji) were regarded in similar terms as the blades for a kris and chanting a mantra while forging a spur was believed to imbue it with magical power.
This is a bamboo tube filled with seven iron cockspurs. Cockspur cases were made and used in many parts of Indonesia, I'm not sure where this example comes from, possibly Lombok, an island adjacent to Bali.
Height of the bamboo tube: 14,6 cm - 5,7 inch.
