My "Grade 8" Oil Filter Wrench

The little Fram would just crush under the teeth of the chain auto parts store oil filter wrench (three times using various starting points), then still would not budge after driving a Craftsman flat blade screwdriver through its heart and hammering on the handle. Finally resorted to some high-caliber artillery, a six-inch grade 8 bolt and a yard-long persuader used for leverage. Even so, just barely got it to break free by the skin of my teeth.

How was that filter installed? Sounds like they tightened it with a filter wrench. Beleive it or not, hand tight is plenty.
