Flat file (far left), a general-purpose file for fast removal of metal. Has a slightly tapered shape and double-cut faces, with a single cut along the edges. Good for keeping paint scrapers clean and sharp.
Hand file (far center). Similar to flat file, but with parallel edges; one edge is safe, or uncut, to prevent marring the work.
Pillar file (near center). A thin file, fits into narrow grooves and slots.
Square file (near right). Shaped to fit into recesses, angles, and holes for filing. Like the flat file, it tapers toward the end.
