Abstract: A pair of pruning shears includes a first handle, a blade seat, a blade, a second handle, a connecting member, and a spring. Thus, the spring mounted between the first handle and the second handle is disposed at an oblique state, thereby decreasing the pressing force applied on the user's hand, so that the user can hold the grip of the first handle and the second handle smoothly and comfortably, thereby facilitating the user operating the pruning shears.

Abstract: A shear device includes a pair of handles having one end pivotally coupled together at a pivot shaft, and a pair of cutter blades secured to the handles and each having a notch. A knob is slidably engaged in the handles and includes a pin for engaging with the notches and for securing the cutter blades together. A button is slidably engaged in one of the handles. The knob includes a pawl for hooking to the button and for securing the knob to the button such that the knob may be secured to the handles and such that the pin may not be disengaged from the notches of the cutter blades.
