ABSTRACT:
An improved cutting mechanism for a pole pruner; the cutting mechanism includes a head mounted on the upper end of an elongate vertical pole. The head has an upwardly, radially forwardly and downwardly turned, recurvant, work-engaging hook defining a downwardly and laterally opening hook opening with an inner shearing edge. An elongate normally vertically extending cutting blade is normally positioned adjacent one side of the hook and is pivotally mounted at its upper end to pivot forwardly and upwardly across the hook opening. The cutting blade has an elongate actuating lever normally projecting upwardly and rearwardly from its upper end. The lever arm is pivoted rearwardly and downwardly by manually applied force to pivot the blade from its normal position across the hook opening. The cutting blade has a lancet blade with a substantially vertical forwardly disposed primary cutting edge, a substantially horizontal upwardly disposed secondary cutting edge and a forwardly and upwardly disposed tip normally projecting into the lower rear portion of said hook opening and engaging work moved up into engagement in said hook opening and preventing displacement of said work from said hook opening in advance of said cutting blade.
