The Crescent Nicholson warding files with a smooth-cut pattern, are primarily intended for locksmiths to use in repairing or filing down the ward notches in keys. The thin rectangular shape is suitable for working in narrow spaces, while double-cut pattern and smooth coarseness make these fast-acting files that still leave smooth edges.
