Pooring honey from an ordenary cup or a special vessel is always hard.
Your fingers get always sticky. But I have designed a cup that does not let any honey rest on the outer surface.

It is actually simple. It looks like teeth, the honey passes throught them, and then they are closed by a mechanical system (like cisors), and the honey that rests on the outside is cleaned by another mechanical system the same way that the eyes clean the dust on them.
