ABSTRACT:
A wrench particularly adapted for removing automotive oil filters and similar cannister type filters without crushing the relatively thin outer shell of the filter. The wrench includes a relatively wide, flat, flexible metal strap having a length less than the circumference of the filter and pivotally connected at one end to an end of a rigid handle. The strap carries a pivotally mounted hook at its opposite end and the hook is adapted to engage the cross pins of a link chain which is pivotally connected at one end to the handle at a point spaced inwardly from the end of the handle to which the strap is attached.
