A normal 2 handed sword weighs 5-8 pounds (granted, there’s a very broad range of what constitutes a “two handed sword”), whereas a bearing sword weighs 14-15 pounds, and are roughly 7 and a half feet long, including the handle. Not impossible to swing, of course, but probably foolish to actually wade into a battle with one, since even regular sized weapons and moderate armor will sap someone’s endurance pretty quickly. Bearing swords are, as far as I’m aware, purely ceremonial.
