Abstract: One or more coupling mechanisms for a modular system are provided. The coupling mechanisms work with modular units in a system, such as modular tool storage units. The coupling systems are configured to couple with and integrate various objects into the modular system, such as bags and tools. The coupling systems include various configurations of male and female couplers to facilitate coupling with utility modules including corresponding male and female couplers.

Abstract: Various embodiments of a faucet wrench are provided. The faucet wrench includes a first insert that includes multiple inner jaw surfaces. The multiple inner jaw surfaces are each configured to engage workpieces of different sizes. In specific embodiments, the first insert includes a plurality of stackable components, each with multiple inner jaw surfaces. The plurality of stackable components can be interchanged and/or reoriented by a user to allow the user to select a preferred inner jaw surface to be used for a given task. In further specific embodiments, the first insert includes a pivotable wedge that allows the faucet wrench to be used in different orientations. In specific embodiments, the faucet wrench also has a second insert that includes multiple work surfaces for engaging an additional variety of workpieces.
