ABSTRACT:
A pole type pruner with an enclosed blade type construction whereby the blade is supported from the sides thru the whole cutting cycle so a thinner blade can be used for easier cutting and less distortion to the wood and bark. This distortion is further reduced by a more choke type, more confining type cutting method, and because regardless of tree limb direction or position the cutting angle of the blade can be directed nearly perpendicular to the limb due to the use of a pole section angle changing box. A pruning saw, one end pivoted to the end of the cutter blade handle, sheathed when desired, being used as part of the cutter blade pull system makes the saw always conveniently available to be pivoted to proper angle of saw direction and clamped to the cutter blade in this position for saw pruning and yet eliminates an awkward outward projection when it's not used for saw pruning. The twist type of blade return coil spring used also reduces any awkward projection. A steel cable removably hooked to the other end of the pruning saw and confined always in near proximity alignment to the pole sections and pulled by the inherent leverage of a windlass as part of and attached to a bottom pole section creates a power and ease of blade pull and cutting really beneficial to tree pruning.
