Uncanny

Many - in my frustrated opinion, too many - recipes call for a six-ounce can of tomato paste. Are they actually calling for "as much tomato paste as one can reasonably extract from a six-ounce can"?

Forks, spoons, and knives - even those which actually fit into those blasted little cans - all seem to leave a significant fraction of the goo behind.

Is there some sort of special implement or arcane procedure which actually gets close to the full six ounces out?
