They can weld themselves on, can't they?
The mistake many people make when trying to remove a stubborn filter is to 
grip the thing in such a way as to deform the ring. This is 
counterproductive as it makes it even harder to remove.
Whatever tool you use, make sure it grabs as much of the ring as possible 
and be aware that you can warp the ring.
