Which filing technique is NOT recommended?

• A. Moving from corner to center of free edge
• B. Sawing back and forth across free edge
• C. Moving along the free edge in one direction
• D. Holding the file at a slight angle

Answer: (B)

Filing should protect the nail while creating a smooth, even edge, so you want light, controlled strokes in a single direction. The tip of the nail—its free edge—needs to be shaped with continuous motions that follow the nail’s natural contour. A back-and-forth sawing motion across the free edge introduces a lot of friction and heat, which can micro-tear or thin the nail plate, roughen the edge, and create jaggedness or splitting. It also can dull the file quickly and makes it harder to control the shape. In contrast, moving from corner to center helps round and refine the tip without creating abrupt edges, and moving along the free edge in one direction with a slight angle keeps the surface smooth and aligned with the nail’s curvature. Keeping pressure light and strokes steady minimizes damage and yields a cleaner result.
