The Nicholson pattern makers cabinet rasp file has a half-round shape with medium American pattern rasp-cut teeth for aggressive removal of wood or soft materials in holes, curves, and corners in cabinet making. The file tapers toward the point in width to ease access into holes and grooves. The rasps density of six or more rows of teeth per inch provides a smoother finish than regular cabinet rasps. It has medium, single-cut American pattern teeth on the edges for smoothing with a medium-smooth finish. The tang can be used with an optional handle for secure gripping (sold separately).
Hand files are used to remove material and smooth and shape workpieces. They have forward-facing cutting teeth and cut when pushed over either a stationary or rotating workpiece. Single-cut teeth are single rows cut diagonally across the width of the file. Double-cut teeth have two sets of rows cut in opposite directions. American pattern files have three coarseness grades. Coarse, also known as bastard cut, is suitable for efficient, heavy material removal where finish is not a concern. Medium, also known as second cut, offers average material removal and finish quality. Fine, also known as smooth cut, provides the smoothest finish. Swiss pattern files have eight coarseness grades, from 00 (coarse), 0 (medium), and 1 to 6 (fine to finest), offering a smoother finish than equivalent American pattern files. For Swiss pattern files the length of the tool is the length of the blade, not counting the tang, which is the pointed end fitted for a handle; for American pattern files the length of the tool is its entire length, including the tang.
