JH> But, for a more complex problem than describing the shape of staples,

JH> 1.  Please describe the shape of a "hog ring" so that all can

JH> 2.  Why are they called that?
JH> 3.  How are they currently used?

1 - You mean those big (or little) rings made from wire that look
    like a nice round letter "C"?
2 - I don't know.
3 - I have a bunch holding the upholstery to my car's seat frames.
(I cheated...we still have a pair of hog ring pliers in the old
toolbox, and I once asked "what are those weird things for?".
