He could easily have stolen the sword from whoever actually managed to take it from the stone and reunite it with the dagger. According to legends, Excalibur can only be weilded by one person. The sword choses the hero, not the other way around. The name "Killian Jones" emblazoned on the blade, only solidifies this classic concept. Hook would not be able to control Excalibur, unless he was the one who pulled it from the stone.

Similar to how the in LotR, the Shards of Narsil (reforged into Andulril) can only be weilded by the King of Gondor. Or how the Elder Wand in HP, would not attack its true owner.
