War hammer in the context of "Heavy cavalry"

A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong).

Hammering is use of a hammer in its strike capacity, as opposed to prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact; for extreme impact, concurrent motions of the torso and knee can lower the shoulder joint during the swing to further increase the length of the swing arc (but this is tiring). War hammers are often wielded in non-vertical planes of motion, with a far greater share of energy input provided from the legs and hips, which can also include a lunging motion, especially against moving targets. Small mallets can be swung from the wrists in a smaller motion permitting a much higher cadence of repeated strikes. Use of hammers and heavy mallets for demolition must adapt the hammer stroke to the location and orientation of the target, which can necessitate a clubbing or golfing motion with a two-handed grip.

The English term lance is derived, via Middle English launce and Old French lance, from the Latin lancea, a generic term meaning a spear or javelin employed by both infantry and cavalry, with English initially keeping these generic meanings. It developed later into a term for spear-like weapons specially designed and modified to be part of a "weapon system" for use couched under the arm during a charge, being equipped with special features such as grappers to engage with lance rests attached to breastplates, and vamplates, small circular plates designed to prevent the hand sliding up the shaft upon impact. These specific features were in use by the beginning of the late 14th century.

Though best known as a military and sporting weapon carried by European knights and men-at-arms, the use of lances was widespread throughout East Asia, the Middle East, and North Africa wherever suitable mounts were available. Lances were the main weapon of lancers of the medieval period and beyond, and these troops also carried secondary weapons such as swords, battle axes, war hammers, maces, and daggers for use in hand-to-hand combat, since the lance was often a one-use-per-engagement weapon, becoming embedded in their targets or being broken on impact. Assuming the lance survived the initial impact without breaking, it could also prove inappropriate for more static, closer engagements where its length became a hindrance.

The horseman's pick is a weapon of Middle Eastern origin used by cavalry during the Middle Ages in Europe and West Asia. It is a type of war hammer that has a very long spike on the reverse of the hammer head. Usually, this spike is slightly curved downwards, much like a miner's pickaxe. The term is sometimes used interchangeably with war hammer. A metal-made horseman's pick called "nadziak" was one of the main weapons of the famous Polish Winged Hussars. A weapon of late make, the horseman's pick was developed by the English and used by billmen. It was used with great success during the Hundred Years' War. A use of the horseman's pick was to tear men from their mounts.

The horseman's pick was often used as a means to penetrate thick plate armour or mail which the standard sword could not. However, a number of drawbacks limited the weapon's effectiveness. Its relative heaviness made it unwieldy and, thus, easily avoided. The injury caused by the weapon was also small and rarely immediately fatal. Additionally, if swung too hard, the weapon often became embedded in the victim or their armour, making retrieval difficult.
