You should not use a wrench to install an oil filter. Just get it as tight as you can by hand. Make sure your hand is dry, meaning no oil, water, or sweat on it. If you need to, ask GI Joe to use his kung-fu grip.
What helps a lot is getting filters that have a rough outer texture to help grip. You might then be able to get it loose by hand when the filter isn't too hot. I have a "finger" wrench similar to the one in PJToledo's picture if one is a little too tight for that.
The screwdriver trick was common in the 1970s, but filters for American cars were made of thicker metal then. In the 1980s those started getting made a lot cheaper. I tore off the body of a filter on a Toyota once and never removed one that way again.
I used to like K&N filters with the nut on the end, but recently there have been complaints in other forums about poor overall quality and leaks around the spot welds that attach the nut. I use an Amsoil oil filter on my Ranger and can usually get it off by hand. It seems to have slightly greater capacity than the normal aftermarket filters.
