Te rabatan te matau. Shank. It has been filed from either te aubunga (clam shell) or cassus shell. It has been fractured in two. When whole, both parts would make one part of a composite te matau (fish hook). They are hard in material, off-white in colour, matte in surface texture and smooth to touch. The cross-sections of the fractured areas show the white opacity of shell's hard material. It was originally filed into a cylindrical form. One part has been tapered into a point where a circular perforation has been drilled through its depth for the purpose of inserting and attaching te ao (line). The other part portrays a rim that has been carved out for positioning the lashing of cordage. In addition to this, a furrow has been filed into the centre of the cross-section, this would be for the purpose of positioning te tabon te matau (point).
