Hang in there, but not by the neck

Why are there so many clothes hangers that come to a dull point at the end, and why do I own these hangers? All clothes hangers should have rounded, non-snaggable ends. Sometimes you drape a clothing item or two over the dowel from which the hangers hang (hence the name).  When it's that item's turn to be put on, you pick it up off the hanger bar, but often it will get caught on a hanger end or two.  Not the end of the world, but bad news for that sweater.
