Club (weapon) in the context of "Baseball bat"

A weapon, arm, or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime (e.g., murder), law enforcement, self-defense, warfare, or suicide. In a broader context, weapons may be construed to include anything used to gain a tactical, strategic, material, or mental advantage over an adversary or enemy target.

While ordinary objects such as rocks and bottles can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs and swords to complicated modern firearms, tanks, missiles and biological weapons. Something that has been repurposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser.

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.

A baton (also truncheon, nightstick, billy club, billystick, cosh, lathi, or simply stick) is a roughly cylindrical club made of wood, rubber, plastic, or metal. It is carried as a compliance tool and defensive weapon by law-enforcement officers, correctional staff, security guards and military personnel. The name baton comes from the French bâton (stick), derived from Old French Baston, from Latin bastum.

As a weapon a baton may be used defensively (to block) or offensively (to strike, jab, or bludgeon), and it can aid in the application of armlocks. The usual striking or bludgeoning action is not produced by a simple and direct hit, as with an ordinary blunt object, but rather by bringing the arm down sharply while allowing the truncheon to pivot nearly freely forward and downward, so moving its tip much faster than its handle. Batons are also used for non-weapon purposes such as breaking windows to free individuals trapped in a vehicle, or turning out a suspect's pockets during a search (as a precaution against sharp objects).

Nuijamaa (Finnish: [ˈnui̯jɑˌmɑː]; literally translated the "club land") is a former municipality in the province of South Karelia in Finland. The municipality had 1,199 inhabitants and an area of 136 km² in 1988. Nuijamaa was a Finnish-speaking municipality. Nuijamaa bordered the municipalities of Lappee, Lappeenranta, Lauritsala, Taipalsaari, Lemi, Luumäki, Ylämaa, and Joutseno. It also shared a border with Russia. It is 26 kilometres (16 mi) from Nuijamaa to the city center of Lappeenranta and 39 kilometres (24 mi) to the medieval town of Vyborg, Russia.

Before the Winter War, Nuijamaa had an area of 356 km (137 sq mi). With the Continuation War in 1944, 220 km (85 sq mi) of the municipality was ceded to Russia. In 1975, an international border with Russia opened in Nuijamaa. The total crossings in 2007 were over 1.7 million.

A mace is a blunt weapon, a type of club or virge that uses a heavy head on the end of a handle to deliver powerful strikes. A mace typically consists of a strong, heavy, wooden or metal shaft, often reinforced with metal, featuring a head made of stone, bone, copper, bronze, iron, or steel.

The head of a mace can be shaped with flanges or knobs to increase the pressure of an impact by focusing the force on a small point. They would bind on metal instead of sliding around it, allowing them to deliver more force to an armored opponent than a traditional mace. This effect increased the potential for the mace to injure an armored opponent through weak spots in the armor, and even damage plate armor by denting it, potentially binding overlapping plates and impeding the wearer's range of motion. Medieval historian and re-enactor Todd Todeschini (AKA Todd Cutler) demonstrated this effect with period accurate equipment in a series of tests on video.

Stick-fighting, stickfighting, or stick fighting, is a variety of martial arts which use blunt, hand-held "sticks" for fighting, most typically a simple, non-lethal, wooden staff or baton. Schools of stick-fighting exist for a variety of weapons, including gun staffs, bō, jō, bastons,Naboot, and arnis sticks, among others. Cane-fighting is the use of walking sticks as improvised weapons. Some techniques can also be used with a sturdy umbrella or even with a sword or dagger still in its scabbard.

Thicker and/or heavier blunt weapons such as clubs or the mace are outside the scope of stick-fighting (since they cannot be wielded with the necessary precision, relying on the sheer force of impact for stopping power instead), as are more distinctly-shaped weapons such as the taiaha used by the Māori people of New Zealand, and the macuahuitl used by the Aztec people of Mesoamerica in warfare.
