Abstract
The present invention relates to a folding knife handle, which includes a first housing pivotally connected to a blade and formed with an arcuate guide groove through which a stud of the blade passes, a pushing element movably located on the first housing and having one end exposed from the handle, a pressing element connected to the pushing element and having one end provided with a pressing plate, and a second housing assembled to the first housing to cover the pressing element. When the stud is located at a first end of the arcuate guide groove and the pressing plate doesn't press against the stud, the blade is fully received in the handle and, when the pressing plate presses against and moves the stud toward a second end of the arcuate guide groove, the stud is driven by a resilient member to move the blade fully out of the handle.
