Abstract
A garden pruner has a leaf spring 14 secured at its outer end to one of the handles (12a) and engaging the other handle (11a) at its inner end. A slider (15) on the one handle (12a) slidably engages the leaf spring and is movable to vary the length of the spring between the slider and the inner end of the spring and thereby vary the spring force and spring rate.
