Equipment

Knights used a variety of weapons, including maces, axes and swords. Elements of the knightly armour included helmet, cuirass, gauntlet and shield.

The sword was a weapon designed to be used solely in combat; it was useless in hunting and impractical as a tool. Thus, the sword was a status symbol among the knightly class. Swords were effective against lightly armoured enemies, while maces and warhammers were more effective against heavily armoured ones.

One of the primary elements of a knight's armour was the shield, which could be used to block strikes and projectiles. Oval shields were used during the Dark Ages and were made of wooden boards that were roughly half an inch thick. Towards the end of the 10th century, oval shields were lengthened to cover the left knee of the mounted warrior, called the kite shield. The heater shield was used during the 13th and the first half of the 14th century. Around 1350, square shields called bouched shields appeared, which had a notch in which to place the couched lance.

Until the mid-14th century, knights wore mail armour as their main form of defence. Mail was extremely flexible and provided good protection against sword cuts, but weak against blunt weapons such as the mace and piercing weapons such as the lance. Padded undergarment known as aketon was worn to absorb shock damage and prevent chafing caused by mail. In hotter climates metal rings became too hot, so sleeveless surcoats were worn as a protection against the sun, and also to show their heraldic arms. This sort of coat also evolved to be tabards, waffenrocks and other garments with the arms of the wearer sewn into it.

Helmets of the knight of the early periods usually were more open helms such as the nasal helmet, and later forms of the spangenhelm. The lack of more facial protection lead to the evolution of more enclosing helmets to be made in the late 12th to early 13th centuries, this eventually would evolve to make the great helm. Later forms of the bascinet, which was originally a small helm worn under the larger great helm, evolved to be worn solely, and would eventually have pivoted or hinged visors, the most popular was the hounskull, also known as the "pig-face visor".

Plate armour first appeared in the 13th century, when plates were added onto the torso and mounted to a base of leather. This form of armour is known as a coat of plates, and was initially used over chain mail in the 13th and 14th centuries, at the time of Transitional armour. The torso was not the only part of the knight to receive this plate protection evolution, as the elbows and shoulders were covered with circular pieces of metal, commonly referred to as rondels, eventually evolving into the plate arm harness consisting of the rerebrace, vambrace, and spaulder or pauldron. The legs too were covered in plates, mainly on the shin, called schynbalds which later evolved to fully enclose the leg in the form of enclosed greaves. As for the upper legs, cuisses came about in the mid 14th century. Overall, plate armour offered better protection against piercing weapons such as arrows and especially bolts than mail armour did. Plate armor reached his peak in the 15th and 16th centuries, but was still used at the beginning of the 17th century by the first Cuirassiers like the London lobsters.

Knights' horses were also armoured in later periods; caparisons were the first form of medieval horse coverage and was used much like the surcoat. Other armours, such as the facial armouring chanfron, were made for horses.
