Abstract: A multi-purpose wedge tool may include a body having a wedge surface, a first base surface, a second base surface, and a sidewall surface that may be coupled together in a triangular prism shape, such as to form a wedge. The first base surface and second base surface may be generally parallel to each other and may be separated by a body recess that may be depressed into the body. A body projection may extend over a portion of the body recess, and the body projection and body recess may allow the tool to function as a spanner wrench for gripping and turning objects, such as the lugs of hose couplings by applying a moment to the lug of the coupling. The body may include one or more body apertures that may be sized and shaped to receive portions of valves or fittings that are typically manipulated by their rotation.
