Abstract
A garden shears is provided with replaceable knives mounted on elongated grips which are connected at a pivot joint that is constructed of a steel bushing that takes up radial loads (shear and flexure). Axial loads are taken up by a screw bushing which passes through the steel bushing and a joint screw threadably engaged with the screw bushing. Both the joint screw and the screw bushing have widened shallow heads with slightly convex surfaces that pass into surfaces of the shears. The replaceable knives are supported at the rear by extensions of the respective grips in a manner such that the knives are not required to take up bending moments.
