For years, Milwaukee's Sawzalls have been valued for their outstanding ability to cut through almost any material: wood, nail-embedded wood, steel, cast iron, aluminum, brass, drywall, composition materials, hard rubber, cement, brick, plaster, and fiberglass. The Super Sawzall features variable-speed control, with a speed control dial for faster cutting and better efficiency and control over a wide range of materials and applications. The blade is reversible, too, allowing you to cut upside down in tight spaces. For those of you who've grown up with Sawzalls, you'll appreciate the addition of the handy Quik-Lok blade clamp, which lets you change blades quickly without having to use a hex wrench; this feature is especially convenient when you're cutting hard materials, such as steel, a situation in which blades break frequently. There's also a handy quick lever adjustment for the shoe. We really like this tool's counterbalancing mechanism, which reduces some of the unavoidable vibration found in reciprocating saws. The difference you feel when operating this tool, compared to nonbalanced saws, is significant: the Super Sawzall is still extremely powerful, yet it has a smooth feel. As a result, of course, you can work longer with less fatigue than you can using other, unbalanced saws. Another significant feature is the clutch, which absorbs shock and impacts to the internal mechanics caused by sudden blade lockups (typically encountered during extreme use). While this is unquestionably a heavy tool, it does have a comfortable, ergonomically designed rubber grip that gives you a solid hold. And you can rely on the Super Sawzall to handle the most difficult jobs, either at home or at work. --Tim Block
