Oil filter wrench
 An improved filter wrench is shown for applying torque to a canister-type oil filter to engage and disengage the threaded end thereof from an engine block. The tool includes a wrench body having a larger and smaller aperture for reversibly receiving smaller and larger relatively sized filter canisters. A separate driver adapter engages the exterior surface of opposite extents of the wrench body when different sized filters are being engaged within the larger and smaller apertures of the wrench body respectively, so that a variety of sizes of filters can be driven by the wrench.
