The fundamental purpose is not to make a strike harder for the opponent, but to make the act of blocking safer for the defender. Without them, the dense bone of the ulna and radius is directly exposed to the hard shin bone of an opponent, a collision that frequently results in painful bruises, deep hematomas, and even fractures.
