Abstract
A pruning clipper includes a pair of handles each having a distal end and a proximal end, with the handles being pivotally connected to each other close to the proximal ends of the handles. A first blade is connected to the proximal end of one of said handles, and a second blade is connected to the proximal end of the other handle. A chemical storage tank is connected to the distal end of one of said handles for storing a chemical to be selectively applied to vegetation. A bulb is connected to the proximal end of one of the handles, with the bulb being connected to the tank using a first connecting tube. A dispensing member extends along the side of one of the blades and beyond the blade to a dispersion point, and the dispensing member is connected to the bulb using a second connecting tube. As a result, the user will be able to cut the vegetation as desired using the clippers, and selectively dispense an herbicide as desired by the user.
