Heh, yeah, I've used it too. I almost felt embarrassed to mention that, but hey, if you need to use it as a last resort or to relieve stress by stabbing something... it does work. My socket type doesn't really work extremely well unless I wipe off the oil filter AND the rubber feet of the tool (which I had to super glue on the metal arms because the tool was cheap and they kept slipping and sliding and popping off because I dropped it in the oil pan once - d'oh!) with some Brakleen (notice a trend?) and even then I have to grip it with my hand a little sometimes to keep the tool from slipping. And no, I'm not over-tightening my filter - just hand-tightened between 2/3-3/4 of a turn once it makes contact. I guess I just have some moments of laziness. I bet one of those rubber jar-gripper pads would probably get it off too. Anyway, just figure out what works for you and roll with it. There's more than one way to skin a cat. Meow.
