The Savage Folding Jab Saw/Utility Knife is one heavy-duty tool that is both a saw and an integrated utility knife, cleverly designed in a rugged metal case with a comfortable, cushioned handle. An industrial, screw-down bolt holds blades tight, but they can be changed easily and fast. The tool accepts any reciprocating saw blade, so you can use it for dozens of projects, from trimming trees to cutting metal conduit or plastic pipe. And it's the perfect drywall saw. Saw blades can be locked in a straight or angled position for maximum flexibility. The onboard utility knife is top quality. It comes with a sturdy carrying case that holds the tool and extra blades, with a built-in belt clip, three saw blades and a utility blade.
