Abstract
A pruning shear device includes a hook formed on the upper portion of a handle for engaging with a tree limb. A bar has one end pivotally coupled to the handle and bar an oblong bole. A cutter blade is pivotally coupled to the handle and has a free end slidably engaged in the oblong hole of the bar. A lever has one end pivotally coupled to the handle and a link pivotally couples the middle portion of the lever to the bar for allowing the lever to rotate the bar and the cutter blade with less force.
