Te rabatan te matau. Shank. Made from te bwaeo (mother of pearl shell) and cut from the hinged area. This is one part of te matau (fish hook), otherwise can be referred to as te kaneati (fish hook of mother of pearl). It has been cut into a length with a short width. The depth of te bwaeo can be seen from the sides and the way in which the hinge is raised. A circular perforation has been drilled through depth of the hinge segment. This end of the length has also been filed and tapered into a short point. Opposite, where te rabatan te matau becomes more flat in depth, four short nodes have been filed out, similar in shape to a fish tail end. This is where tabon te matau (point) would be lashed to with some kind of cord, in most cases the use of kora (coconut sennit fibre cordage) would be used. Te bwaeo is off-white in colour with some shimmer and pale yellow burnishes on both sides. Some transparency and small cavities remain across the exterior.
