If I really need a tool, then I use a large pair of pliers that looks something like this:
I don't normally use it since I hand-tighten the filter and never had any leaks.
I grab the old filter and the new one and make them kiss each other on the rubber ring as I twist them clockwise/counter-clockwise (I know too much romance in the garage), that way the rubber on the new filter gets the proper amount of lubrication.
Afterward, I spin it on slowly until the filter makes contact with the engine and comes to a stop. At that point, I turn it (single hand) one full turn or until I can no longer turn it without turning purple (of course, whichever comes first).
I have used the same exact oil filter on 3 different make bikes and have been very happy: Hi-Flo 303
