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 of the wrench body when a filter canister is being received within the larger aperture and is itself received within the larger aperture when a filter canister is being received within the smaller aperture of the wrench body.
