Abstract: A method which can be done in a procedure of separating a small area of nail bed flesh from the nail plate's underside, where the nail plate and nail bed join, at the forefront, to an extent back toward the base of the fingernail. A visible convex line (10), across the top of the nail plate, visible due to the translucency of the nail plate, where the nail plate and nail bed join, indicates the precise location of the forefront of the nail bed, thus of the nail bed flesh. A second and identical line, simulated convex line (12), just below and adjacent to line (10), on the nail plate (20), indicates the extent to which the nail bed flesh is separated. An intermediate area (18), formed in a concavo-convex shape, between the two identical convex lines, is the area of separation of nail plate and nail bed flesh; extending the full width of the nail bed, and from approximately 0.5 or 0.7 mm, up to approximately 2.0 mm longitudinally of the nail bed.
