Nail care method using nail bit without using nipper

A nail care method using a nail bit, comprising:

• 1) a step of forming a reference line by separating a connection portion between an eponychium and a cuticle;
• 2) a step of removing the cuticle and loose skin located below the separated reference line;
• 3) a step of removing loose skin from a side line and building an eponychium wall;
• and
• 4) a step of removing the cuticle at a boundary between the eponychium and a nail and forming an undercut beneath the eponychium,
• wherein the step 1) includes:
• pressing down a fingertip above the nail so that skin above the cuticle is slightly pushed toward the cuticle;
• forming a shadow line between the displaced eponychium and the cuticle;
• and performing cutting while moving a cutting bit along the shadow line in a clockwise or counterclockwise direction such that a cutting surface of the cutting bit is parallel to the shadow line, to form the reference line at the connection portion between the eponychium and the cuticle,
• wherein the step 2) includes removing the separated cuticle and loose skin by moving a diamond bit in the clockwise or counterclockwise direction, or completely removing the remaining cuticle and loose skin by moving the diamond bit from a lower portion of the eponychium toward the tip of the nail,
• wherein the step 3) includes removing loose skin existing on the side line and an inclined surface portion of the eponychium line using an upper portion and an edge portion of a metal stick bit, allowing an axial direction of the metal stick bit to be perpendicular to the side line and the eponychium line, and moving the metal stick bit from one end of a side line of the nail to the other end of the side line along the eponychium line in the clockwise or counterclockwise direction,
• wherein the step 4) includes:
• in a skin-up state in which the fingertip above the nail is pushed upward toward the back of the hand to expose the cuticle existing at the boundary between the eponychium and the nail, removing the cuticle and loose skin while a top side (abrasive surface) of the metal stick bit is aligned parallel to the nail and is moved from one end of the side line of the nail to the other end of the side line along the eponychium line in the clockwise or counterclockwise direction to additionally remove the cuticle and loose skin, and forming an undercut at the boundary between the eponychium and the nail.
