RangerPilot: I could hammer through the end like you said, but I can't see it being any better than the first filter wrench I tried. It didn't slip while I was giving it all I had .

So I got the new filter wrench with the strap and "Webb Lock Design". Unfortunately it looks like the space is too tight to work this thing to its full potential. I wrestled with it for several minutes but no go. I'll give it another shot when I've got some daylight before finally throwing in the towel. Thanks for all the input guys. I'll take some pictures tomorrow of the filter's space if anyone's interested in how small it really is.
