An oil filter wrench having a base, a main gear, a plurality of claws each having a gear portion and an arm configured to engage an oil filter. The gear portions are rotatably disposed within the base and configured to engage the main gear such that when the main gear rotates; the arms correspondingly extend or contract relative to the base. The oil filter wrench also includes a main spring. The main spring is disposed within a cavity defined by the main gear. The main spring is configured to selectively bias the main gear toward rotation in either a first direction or a second direction opposite to the first direction. The oil filter wrench is characterised in that it also includes a switching mechanism a switching mechanism. The switching mechanism is configured to selectively toggle between a first position and a second position. In the first position, the switching mechanism engages a first tine of the main spring such that the main gear is biased to rotate in the first direction. In the second position, the switching mechanism engages a second tine of the main spring such that the main gear is biased to rotate in the second direction. The switching mechanism is toggled between the first and second positions by respectively engaging a first pin or a second pin that is integrated into one of the plurality of claws.
