The Klein 31737 Folding Jab Saw is a versatile hand tool designed for cutting through various construction materials. Its fast cutting carbon steel blade, with triple ground teeth, can rip or tear efficiently in both directions. The saw's lockback mechanism securely holds the blade open at 125-degrees and fully open at 180-degrees, providing access to hard-to-reach spots. The folding design keeps the blade from piercing through tool pouches and bags, ensuring their protection. The saw features a cushioned handle-end for easier palming and a comfortable, non-slip grip. A lanyard hole is available for tethering. This folding jab saw is suitable for cutting through drywall, wallboard, plywood, plastic, and other construction materials.
