The Swanson Savage Jab Saw (SVK666) is the Swiss army knife of the drywall trade. At one end is a two-position jab-saw blade, and at the other a utility knife. The saw end is designed to accept any reciprocating saw blade – which can be swapped out by twisting off the holder piece and popping in a replacement. For added safety, the flip-out utility knife locks when it's in the "out" position and must be released before closing. The tool comes in a belt-worn sheath that has room for extra blades.
