Pole-mounted pruner hook

An improved single-pass hook and blade type agricultural shear with a central pivotal axis. The shear includes an elongate hook with an outer end and an inner end pivotally supported about said axis. Said hook has a substantially radially extending circumferentially disposed concave branch supporting shearing edge. The shear next includes an elongate blade with an outer end and an inner end supported about said axis. Said blade has a substantially radially extending circumferentially disposed convex primary cutting edge opposing said shearing edge. The cutting edge has an outer portion and has an inner portion circumferentially offset from said outer portion and has a substantially circumferentially extending radially inwardly disposed intermediate cutting edge extending between the outer and inner portions of said primary cutting edge. The outer portion of the primary cutting edge and the intermediate cutting edge define a sharp pointed lancet blade between the ends of the primary cutting edge. The lancet blade pierces and holds branches engaged in and cut by the shear in advance of said primary cutting edge. The shear includes lever arms to pivot the hook and blade relative to each other and relative to branches engaged therebetween.
