Abstract
Scissors which may be used with equal ease and efficiency by either a left-handed or right-handed person. The scissors include two generally flat rigid, blade portions which are each sharpened on both edges to provide two sets of cutting edges. The blade portions are pivotally connected to one another and each includes a handle portion on one end. One of the handle portions is adapted to fit the thumb of the user while the other handle portion is larger to permit engagement of two or more fingers of the same hand in the normal fashion of scissors use. The thumb handle is pivotally mounted to its respective blade portion to permit pivotal movement from one selected position at one side of the finger handle as used during right-handed operation to a second selected position at the opposite side of the finger handle for use during left-handed operation. A detent or lock is provided to secure and hold the thumb handle in either of the selected positions.
