Abstract: Double strength loppers employ double leverage effects and have two crossed pivoting blades, a main blade and an auxiliary blade, an upper handle and a lower handle correspondingly matching with the two blades, an upper gear at the end of the upper handle and a lower gear at the end of the lower handle. The lower gear matches with the blade driving gear and the blade driving gear matches with the auxiliary blade. When swinging the upper handle and/or the lower handle, a first leverage effect is created from a first fulcrum that is the contact point between the upper gear and the lower gear, while a second leverage effect is created from a second fulcrum that is the contact point between the lower gear and the blade driving gear. Such double levers and double strength effects significantly reduce the force applied upon the handles, therefore reducing the required labor.
