Better balance, more comfort - Fiskars XtendControl X2 Hook Bill Saw Blade Attachment (15 in.) is part of the comprehensive, interchangeable XtendControl pruning system designed to put pruning control in your hands. The 15 in. aggressive triple-grind blade profile offers fast action with a top hook that keeps your cut inline so you can prune with confidence. The X2 blade is compatible with all XtendControl Extension Poles and when combined shifts the weight of pruning action into your hands for less fatigue than working with a top-heavy pruner.
