I'd like to remove two snaprings from an old Hein Werner model K
floor jack. They're pictured at

and

None of the tools in my collection has any chance of
holding on to these things. Does anybody know of a tool
that will get them off?

It's likely possible to use a Dremel tool to notch them
so they can be either grabbed or broken, but that promises
to be a lot of work and somewhat hard on the adjacent metal.
Better ideas would be much appreciated, I don't like any of mine.

Thanks for looking, and any guidance!
