Source: Museum entry book 1847-55: Made on Rio Icanna and made of soft tenacious wood of an apocyneous tree. Stones are chiefly bluish, fine grained granite from the Icanna, broken into fragments of convenient size. Design scratched with the point of a l, arge nail; then with the same a hole is pricked for insertion of each stone and a blow of the nail head secures it in place. The grater thus formed is anointed with the milk of Cuma (Couma dulcis) which is a useful adhesive, not affected by the juice of, mandiocca or moisture. I have seen graters which were decayed and almost worn through at the back while not a tooth had fallen out. Iccana graters are in great request throughout the Rio Negro, Amazon and Orinoco.
