I will buy most
ANY type of oil filter wrench, that could benefit me in getting a stubborn oil filter off. I'm very careful regarding torque, and proper lubrication of the rubber seal / gasket. But in my years maintaining cars I've seen some real messes made from stuck oil filters, along with the disasters that followed with the butchery involved in trying to get them off.
So if I come across a oil filter wrench that could remotely become an asset in my tool box, I will purchase it immediately. Most are not that expensive, and if they are ever needed in a pinch, they'll be worth many times what I paid for them. Fortunately for me, most are still unused. And I hope they stay that way.
