The reason why they are used in a pair is because if you get snagged with the hook you can still attack with the other weapon. If you only have one and it hooks into your opponent you lose your ability to regain the weapon quickly leaving you open for attack if the blow was not fatal. So if you do get your sword snagged you can still attack and can regain control over your weapon and the battle.
