Te rabatan te matau. Shank. Made from te bwaeo (mother of pearl shell) and cut from the hinged area. This one part of te matau (fish hook). 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 and the natural concave of the shell. A small circular perforation has been drilled into the side of the hinge segment where it has been filed and tapered into a short point. Opposite, where te rabatan te matau is more flat in depth, three curved furrows have been filed across the sides and then finished with centre furrow along the end. This is where a tabon te matau (point) would be lashed to with some kind of cord, in most cases the use of kora (coconut sennit fibre cordage). Te bwaeo is off-white in colour with some shimmer on both sides. The exterior shows some porous remains and brown burnishing. Some transparency can be seen along its depth along with some brown burnishing on the surface of the flat end.
