Class E Airspace

You are correct. Keep in mind it may also extend down to 1,200' AGL to include the airway system or even to the ground at some airports.
Class E starts at 14,500 MSL only when Class G extends to the surface below that. Case in point: Class E starts at 14,500 in areas on the "hard" side of the magenta or blue Class E line on the sectional.

EDIT: Went back and read that again. I just got what you meant by "sharp side of the blue."
