measuring a tbsp

is a tablespoon measurement considered flat across the spoon or rounded??? what do the makes of products go by when saying "1 tbsp"?

I use a "real" tablespoon instrument w/the little line on the inside of the lip that denotes where you are to fill up to.

Using silverware type TBSP's won't give you the same measurement.

from what i have been told through the years, its a "big" spoon rounded.
