Spear & Jackson Predator professional 760mm (30 inch) bow saw. Tubular steel frame for extra strength & rigidity. Ergonomic soft feel handle with built-in hand guard for protection. Simplistic design makes blade changes quick and easy. Adjustable blade tensioner improves performance and enables straighter cuts. Two blade options available:. - Peg tooth blade (dry) is for mature or dry wood, with every third gullet extended for high chip removal and is made uniquely for fast and efficient cutting of dry/dead wood (this blade is supplied with the bow saw). - Raker tooth blade (green) is for live and green wood, with every fifth tooth raker and unset, which functions like a chisel to remove the chips out of the green wood.
