A nail clipper includes a clipper body having a front section and a rear section acting as a first handle, the front section including a top plate and a base plate defining a passageway therebetween. The top plate and the base plate each has an aperture substantially aligned to each other and adapted to receive a finger nail therewithin. A blade is slidably positioned in the passageway. The nail clipper further includes a second handle having a front end connected to the blade, and a flexible plate. The first end of the flexible plate is attached to the second handle and the opposing second end of the flexible plate is attached to the first handle. The flexible plate is adapted to normally bias the second handle and the blade in a retracted position rearward from the apertures. However, when the second handle is gripped against the first handle, the bias of the flexible plate is overcome to advance the blade from the retracted position to a forward position in which the cutting edge of the blade passes the apertures to cut a finger nail positioned within the apertures.
