Lefthanded Kayan Mandau

The ‘mandau’, locally also known as ‘parang ilang’, is the characteristic headhunting sword of the Dayak peoples of Borneo, including present-day Indonesia, Malaysia, and Brunei. Traditionally used in headhunting expeditions, the ‘mandau’ is distinguished by its asymmetrical blade, with a concave and a convex edge, allowing for a controlled and effective cutting action. The blades are often decorated with small protrusions, interpreted as genital symbols or as ‘krowit’ (caterpillars), and further embellished with traditional motifs such as ‘aso’ designs, including ‘mata kalong’ and S-shaped elements referred to as ‘mata djoh’. The present example is an uncommon left-handed variant, with the concave edge on the left side. The quality of the decoration, particularly the finely carved hilt, suggests an origin among the Kayan peoples of the Mahakam River region. The antler hilt is elaborately carved with ‘aso’ motifs and features a finely executed rattan-bound grip, secured at the base with ‘damar’, a natural resin. Attached to the hilt are tufts of human and goat hair, traditionally associated with headhunting practices. Antler hilts were generally reserved for accomplished warriors who had successfully taken a head, while non-veterans typically carried examples with wooden hilts. In some contexts, antler hilts were also regarded as auspicious and treated with particular reverence. The scabbard is complete and constructed from two wooden halves, held together by three rattan bindings, one of which shows wear consistent with age. The front is decorated with sections of bone and horn inlay, including at the tip. The mouth of the scabbard is reinforced with a horn ferrule, secured with bone pegs. The reverse features a rattan-bound suspension system and is further adorned with a cord and a tassel of brightly coloured beads, characteristic of Dayak ornamentation. An inscription on the reverse of the scabbard reads “1-7-58 N.H”, which likely corresponds to 1st of July 1858. The initials “N.H” may refer to a former European owner, suggesting the piece was either collected or presented during that period.
