The weapons of an English medieval knight in combat included the long sword, wooden lance with an iron tip, metal-headed mace, battle-axe, and dagger. Trained since childhood and practised at tournaments, the skilled knight could inflict fatal injuries on even an armoured opponent. The sword, symbol of the chivalric code and his noble status, was above all the knight's most important weapon. With a heavy blade one metre in length, a 'great sword' had to be held with both hands and was remarkably stable in design from the 11th to 15th century CE. A mounted knight wielding a lance was a fearsome enough sight but a dismounted one swinging a sword that could sever limbs with one blow was an awesome psychological weapon in itself.
