The ergonomically designed TPR non-slip handle effectively reduces hand fatigue, ensuring comfort even during extended use. The lockback mechanism secures the saw blades firmly in place. Thanks to the ingenious clamping design, it can support both large and small blades. The saw blades are made of high-speed steel, offering excellent wear resistance. The tips of the blades are sharpened, and the blades are hardened, ensuring long-lasting durability. Replacement reciprocating blades are widely available at any tool store. The hand saw's professional clamping mechanism holds both large and small blades securely. With a compact design, this hand saw saves space in toolboxes, making it convenient to carry and store. It can be used to cut materials such as drywall, metal, wallboard, plywood, plastic, and PVC.
