The piha kaetta, pihiya or ‘Kandyan knife’ is a hand knife from Southern India and Sri Lanka. Kaetta means ‘beak’ or ‘bill’, referring to the distinctive shape of the blade, which is straight-backed with a drop-point and curved cutting edge.

The hilt is plated with silver, decorated with patterns in repoussé and chasing. The elongated bolster is decorative with liya-pata, a Sinhalese decorative motif which resembles swirling waves. Though it is of typical pistol-grip form, it is unusual for the hilt of a piha kaetta to be entirely silver-plated. They are generally made of organic materials such as wood, ivory, horn, and coral.

The wooden scabbard is fluted, with silver plating applied to the top half. Bands of silver filigree decorate the top and bottom of the silver plating. The scabbard curls over to form a wave. An 18th century piha kaetta in the Victoria & Albert Museum, London (accession no. IS.168&A-1897), has a similar scabbard.
