A pincer nail correction tool for remedying a pincer nail of a toe as the nail grows by bonding a necessary part separated from the body to the pincer nail. The tool includes a flat operating portion gripped before the necessary part is bonded and rotated in the direction in which the pincer nail is remedied, a thin-sheet abutting portion extending from the flat surface on one side of the operating portion and projecting straight toward the distal end, a thin-sheet engaging portion narrower than the abutting portion in the surface direction and extending from the surface on the other side of the operating portion substantially parallel with the abutting portion, and a bottom extending from one end face of the operating portion toward the distal end and connecting the abutting portion with the engaging portion to form a J-shaped cross-section. The projection length of the abutting portion is longer than that of the engaging portion.
