The present invention provides a Personal Nail Trimmer comprising a battery-powered nail trimmer designed for use on humans by humans. The unit is cylindrical, approximately four inches in length and one inch in diameter, with the lower portion of the handle containing a chamber for the batteries housing a pair of AA-cells batteries, or in another embodiment, one C-cell battery. A thumb-operated On/Off switch is located on the exterior of the plastic housing just above the battery compartment, and the upper portion of the cylinder contains a small electric motor, powered by the battery and terminating in a driveshaft oriented in the center of, and in line with, the cylinder. This driveshaft terminates in a precision filing wheel, a round emery board which revolves via the driveshaft when the motor is activated. A clear plastic, snap-on sheath fits over the end of the Personal Nail Trimmer, and this sheath presents a slot, or in other embodiments, a series of variously sized slots, into which the user presses his or her fingertip and fingernail. Since fingertip size varies not only between the fingers of any one person, but also between, for example, adults and children, several sheath-caps are included to accommodate the range of slot sizes needed.
