Chelik fayllar yoki po'lat raspa

Tarix

Early filing or rasping has prehistoric roots and grew naturally out of the blending of the twin inspirations of cutting with stone cutting tools (such as hand axes) and abrading using natural abrasives, such as well-suited types of stone (for example, sandstone).Relatedly, lapping is also quite ancient, with wood and beach sand offering a natural pair of lap and lapping compound. The Disston authors state, "To abrade, or file, ancient man used sand, grit, coral, bone, fish skin, and gritty woods,—also stone of varying hardness in connection with sand and water."

The Bronze Age and the Iron Age had various kinds of files and rasps. Archaeologists have discovered rasps made from bronze in Egypt, dating back to the years 1200–1000 BC. Archaeologists have also discovered rasps made of iron used by the Assyrians, dating back to the 7th Century BC.
