Gauntlet /ˈɡɔːntlɪt/ is a name for several different styles of glove, particularly those with an extended cuff covering part of the forearm. Gauntlets exist in many forms, ranging from flexible fabric and leather gloves, to mail and fully articulated plate armour.
Historically, gauntlets were used by soldiers and knights. It was considered an important piece of armour, since the hands and arms were particularly vulnerable in hand-to-hand combat. With the rise of easily reloadable and effective firearms, hand-to-hand combat fell into decline along with personal armour, including gauntlets.
Some medieval gauntlets had a built-in knuckle duster. When the hand was bunched into a fist the backhand protection becomes pronounced from the fist just above the knuckles. This allowed the user to utilize the gauntlet as a melee weapon while still protecting the hand from damage when punching. However, against an armed combatant the use of this feature would have been risky, so it was very unlikely that a gauntlet would have been used in this way when a more suitable weapon was within reach. But if the user had no other means to defend themselves the tactics they would have employed would be to attempt to surprise the opponent with this inconspicuous attack, possibly by dodging and countering, aiming for exposed areas of flesh such as the face or weak areas of armour, such as under the arm or the groin.
A "Demi-gauntlet" (also called a "demi-gaunt" for short) is a type of plate armour gauntlet that only protects the back of the hand and the wrist; demi-gaunts are worn with gloves made from mail or padded leather. The advantages of the demi-gaunt are that it allows better dexterity and is lighter than a full gauntlet, but the disadvantage is that the fingers are not as well protected.
Today, gauntlets are mostly used as armour in contact sports, such as fencing, sword fighting reenactments (such as the Society for Creative Anachronisms) and falconry. In industry, gauntlets are commonly used to protect workers from sparks when welding or grinding metal or when handling potentially harmful substances. Protective gauntlets are also sometimes worn by automotive technicians and butchers. Furthermore, they are an integral part of pressure suits and spacesuits, usually made of kevlar or other materials that combine toughness, environmental protection and flexibility. Gauntlets are also provided on some motorcyclist's leather gloves and on snowmobile driver's nylon mittens.
