Yesterday I baked a good old fashioned loaf, the type you would get from the baker in the 1950's. Today I cut off the end - buttered the top - then cut a slice. It was surprisingly easy to do.
Of couse, cutting bread is an art in itself. Early civilizations did not bother. The Romans baked bread that was pre-segmented and could be broken into pieces. Each piece being a portion for a single meal.
