A bit - an hourglass with curved, not straight, "top" and "bottom"
edges, and with a rather fat waist-pinch.  Oh, and straight lines from
the corners to the waist pinch, not the curves most hourglasses have.

Oh, and I forgot to mention, in my enumeration of the bits, the regular
torxes.  Not that I think the omission terribly serious....
