Scraper-commonly known as “scraping planing”, a flat, a curved, both sides with a blade, made of carbon steel, the length of about 20cm, the role of the flat head with the shovel knife, elbow used in addition to angle and rust and dirt; there is also a pointed scraper, elbow end is pointed, used to remove the cracks in the rust and putty and other dirt.
