If we compare the following 2 different design of the sword guard, we can see a big difference there. The 1st one has guard that is curved backward. When your opponent's sword touches your guard, it will slide off. Your opponent cannot take advantage on that "contact point". The 2nd sword has guard that is curved upward. When your opponent's sword touch your guard, your opponent can use your upward curve guard as the leverage and then stab the tip of his sword into your body. Why people design sword guard like the 2nd sword that will give your opponent such advantage? What's your opinion on this?
