A buffer is the correct tool to use for correcting a crooked nail after filing. Buffers are designed to smooth the surface of the nail, helping to even out any irregularities that may arise from filing. By gently buffing the nail, it can help blend the uneven edges and create a more uniform appearance.

In contrast, nail clippers are primarily used to shorten nails and are not suitable for shaping or correcting crookedness. A nail brush is used for cleaning nails and removing debris, and would not address the issue of a crooked nail. Cuticle remover is meant to soften and remove cuticles, and does not have any application in correcting the shape of the nail itself. Therefore, the buffer is essential in achieving a polished and aesthetically pleasing nail shape after filing.
