Abstract
A conventional nail clipper construction is provided including a reversible and convertible pivoted lever for displacing a spring-type arm equipped with a first cutting blade portion toward a base plate equipped with a second cutting blade portion. The base plate, however, includes opposite side flanges between which the spring arm is swingable and the opposing surfaces of the spring arm and base plate and the inner sides of the flanges together define a storage area in which nail clippings may be contained when the clipper is not in use. Further, the structure by which the lever is pivotally supported includes coacting portions of the lever and side flanges of the base plate and functions to enable the pivot axis of the lever to be shifted between front and rear limit positions longitudinally of the spring arm and base plate.
