Versatile and durable, the DeWalt DW3970 High-Tension Hack Saw Frame delivers a unique feature set that makes it a fantastic addition to any craftsman's arsenal. Built up from sturdy aluminum and steel components, this frame features a quick-change mechanism for fast, on-the-job blade changes, a strong, convenient tension adjustment knob, and built-in blade storage. It makes both 45-degree and 90-degree flush cutting easy, and can even be used as a jab saw in tight spaces. Plus its soft grip, well-balanced body, and hand guard provide excellent ergonomics for reduced user fatigue and less skinned knuckles. The hand guard is removable, so you never have to worry about it getting in the way.
