Cardboard paper that has bonded abrasive particles that allows it to be used for scratching, scraping, wareing, polishing, grinding. It is a lime inflection, which means raer, scrape, grind, polish. The abrasive material can be powdered glass, grinding, ground sand. There are also two kinds of sandpaper fish: one is a type of shark from the family Scyliorhinidae (also called red-painting) and another is that of some reef fish in the Family Monacantidae.
The paper with grinding on one side takes its name from the fish 'sanding', whose rough skin was used to polish wood or metal. The lunfa concept for "voracious appetite" can come from the fish, with a formidable denture according to its voracity; or the wear and tear of sandpaper compared to the wear made of food; or be a variant per lime, which may have another origin. In addition 'sanding' is an ancient way of calling bleach water. And it is also the second (as 'you' ) and third (as 'he/she' ) people in singular present indicative mode, and second (as 'you' ) person in singular imperative for the verb sanding.
