Abstract: A hand pruner having a first and second handle, the first handle having a hook, formed at a far end, the second handle having a cutting blade formed at the far end. The first handle and hook and second handle and blade pivotally connected for movement with respect to each other. The blade and second handle having a cup formed between the blade and second handle. The hook and first handle having a cup formed between the hook and first handle. The cutting edge of the hook is formed along two concave intersecting arcs of different diameters, the smaller diameter arc located next to the pivot. The cutting edge of the blade is formed along two convex intersecting arcs having diameters that complement the two concave arcs in the hook cutting edge.

Abstract: A pruning lopper with an adjustable attachment mechanism to provide for versatile cuts of tree branches and shrubs. The attachment mechanism is a ball joint that can rotate in an x-direction, a y-direction, around the axis of rotation of the pole, or any combination of the three. A pulley system internal to the pole prevents entanglement with tree branches while in operation.

Abstract: A saw blade for improved cutting efficiency includes teeth having depths and tip-to-tip spacings that vary as a function of distance from an end of the blade to the tooth, the teeth extending from the plane of the blade at alternating angles and having a recurring pattern of alternate tip beveling.

Abstract: A hand-operated pruning clipper having a multi-function plastic top handle and metal bottom handle with metal bypass cutting blades for cutting twigs and branches. A pair of wire cutting blades and a plastic bag slicing blade are incorporated into the metal cutting blades.
