It’s often and not without merit said that the point is the most dangerous part of the sword. Especially with European swords we see a great emphasis put on thrusting attacks. Now since people had armour as well as swords, attacks could be deflected fairly effectively whether the point or edge were used. Naturally the knights of old had a solution to this. They figured out that if you hit the person with the pommel of your sword, the extra force provided by the weight of it would destabilize your heavily armoured opponent enough to win you the fight.
