The Jab Saw comes with a bimetal plunge tip for drywall, but it has many other uses as well. The blade can be removed and replaced with any hacksaw or reciprocating-saw blade — including wood, metal, and specialty blades — which means the saw can handle a variety of materials, from metal to PVC. It costs about $15.
