Lance

A lance is mainly used in jousting but it is also used when Knights are not fighting in close combat, fighting Griffins is an example of this.

History
When a Griffin attacked Camelot, Arthur and his knights went our riding to defeat it, they used lances while fighting. But Merlin and Lancelot worked together in order to defeat the Griffins themselves after Arthur failed, and he was dismounted of his horse. Lancelot then came in and defeated the Griffin himself (with Merlin's magic) with a lance (Lancelot).

When Camelot held a jousting tournament, knights used lances to compete in the joust, but the assassin Myror killed Sir Alynor to get into the joust himself in order to kill Arthur, he modified a lance so it could point out a spike. He succesfully got into the joust, but he ultimately failed after Merlin's magic tore him off his horse (The Once and Future Queen).

When Arthur, Sir Leon, Merlin and the Knights of Camelot went out riding to make a last attempt on killing the Great Dragon, Kilgharrah, they used lances in combat. But they were all dismounted off their horses, while most of them burnt in the dragon's flames. Arthur made a last attempt to kill him with a lance off his horse, he struck one heavy blow, but the dragon easily pushed him away. Before Merlin stept in and commanded the dragon with his Dragonlord abilites (The Last Dragonlord).

When Arthur was enganged to Gwen, they used lances in a jousting tournament to honour their marriage. But this marked Lancelot's return, he won the tournament, but shortly after, Arthur caught him snogging Gwen... (Lancelot du Lac).
