Reciprocating saws make most home demolition jobs easier and more fun. You can struggle and rip everything out with a variety of crowbars, hammers, and hacksaws or use a reciprocating saw and just cut it free. It really is the ultimate demolition tool. Windows, walls, plumbing, doors and more—just cut and toss. Reciprocating saws cut through just about everything short of a rock. With a sawzall (the brand name of Milwaukee’s tool) you can cut through lumber even if it has nails embedded, they also work well for certain types of automotive repair particularly exhaust systems.
