In this nail clipper, an upper blade body is supported at the front end of the lower blade body so as to be rotatable in the vertical direction, and a case is supported at the rear end of the lower blade body so as to be rotatable in the vertical direction. A leaf spring attached to the lower blade body between the upper and lower blade bodies pushes the upper blade body upwardly, so that the cutting edges of the upper and lower blade bodies are separated from each other.

When the case is rotated to the rear of the lower blade during use, the upper blade is pushed upward by the leaf spring. In this state of use, when the upper blade body is pressed down against the biasing force of the leaf spring, the upper and lower blade edges come into contact with each other. When not in use, when the case is rotated over the upper blade body and pressed downward against the biasing force of the leaf spring, the upper and lower blade bodies overlap each other and are folded into the case.
