Why this is the answer

A FILE is used to SMOOTH, SHAPE, or remove small amounts of material from a surface by ABRASION (the hardened, ridged surface scrapes away material as it's pushed across). ASVAB Shop Information tests shaping/finishing tools. Files come in various shapes (flat, round, half-round, triangular) and coarseness; used on metal, wood, and plastic to deburr edges, smooth surfaces, sharpen, and shape. A RASP is a coarse file for wood. Files cut on the push stroke. Knowing the file's purpose (smoothing/shaping by abrasion) is commonly tested.
