These professional-grade tools, made in the USA, have been used by road crews and arborists for over two generations. The Large Pruner has a 22-1/2" 6tpi blade, curved for full power throughout the stroke, and deep gullets for rapid chip clearance. It will really do the job fast. The two smaller saws have special tri-grind Japanese-style teeth. They have 14-1/2" (closed handle) and 12-1/2" (straight handle) long blades respectively. Both have great balance, and the latter is particularly light in weight. You can see the sheaths for the Professional Pruning Saws separately here.
