Beladau Melayu Riau Ulu Tandok

Very good and rare example of a small side weapon called the beladau, from the southern Sumatran Malay region of Riau Lingga. Very interesting handle made of buffalo horn, and in a phallus form depicting the Hindu deity Shiva’s phallus. Wooden sheath with plain silver bands and a horn bottom tip.

Very sturdy blade with double sharp edges, and an arcing profile that tapers to a pointy tip, having a prominent spine along the middle.

Pamor patterns are not contrasting, which is the norm from the area, due to the non nickel metals used. From the forging lines the arrangements are of the mlumah technique and are of the kulit semangko or melon skin pamor.

Length of blade: 7.5"
Overall length: 11"
Condition: Very good condition.
Age: Krises are traditionally made without any date stampings or engravings of the makers’ name. Although a kris smith or “empu” has his own styles configured together with the dapor and especially the ganjar (cross piece). Obvious age wear and tear, usage, familiarity with forms, motifs and designs, origin and history, mediums and materials used are our guidelines in determining an approximate age. This particular piece, from our experience and knowledge, should go back to the late 18th century.
