With their rapid back-and-forth sawing motion, reciprocating saws chew through nearly anything. This new breed of recip saw can be used one-handed to reach tight spots. Plumber Josh Clack used these four cordless models on the job to hack through wood framing, as well as copper, PVC, and cast-iron pipe.* Here's his report.
*The cutting ability of each saw was tested on five different materials: wood, nail-filled wood, PVC, steel, and cast iron. For each test, a saw was fitted with a fresh blade suited to the material being cut.
