At the urging of several list members I'm giving this one more try.
I've got the Campy freewheel wrench with the insert that allows you to
remove a 13 tooth freewheel. This is the best freewheel wrench ever
made and works when all else fails because it's actually hard enough to
make its own notch. $55 shopped in the US.
