The kampílan is a type of single-edged long sword, used as a traditional blade throughout the Philippine archipelago
The kampílan has a distinct profile, with the tapered blade being much broader and thinner at the point than at its base, sometimes with a protruding spikelet along the flat side of the tip and a bifurcated hilt which is believed to represent a mythical creature's open mouth.
The Maguindanao and the Maranao of mainland Mindanao preferred this weapon as opposed to the Tausūg of Sulu who favoured the barung. The Kapampangan name of the Kampilan was "Talibong" and the hilt on the Talibong represented the dragon Naga, however the creature represented varies between different ethnic groups. Its use by the Illocanos have also been seen in various ancient records.
A notable wielder of the kampílan was Datu Lapu-Lapu (the king of Mactan) and his warriors, who defeated the Spaniards and killed Portuguese explorer Ferdinand Magellan at the Battle of Mactan on April 27, 1521.
The mention of the kampílan in ancient Filipino epics originating from other non-Muslim areas such as the Hiligaynon Hinilawod and the Ilocano Biag ni Lam-Ang is possible evidence for the sword's widespread usage throughout the archipelago during the ancient times. Today, the kampílan is portrayed in Filipino art and ancient tradition.
Physical description 
Among Filipino swords, the most distinguishing characteristic of the Kampilan is its huge size. At about 36 to 40 inches (90 to 100 cm) long, it is much larger than other Filipino swords, and is thought to be the longest, though smaller versions (sometimes called the kampilan bolo) exist. A notable exception would be the panabas, another Philippine longsword, of which an unusually large example could measure up to four feet in length.
Related to the klewang, the blade is narrow near the hilt and it gradually swells in width into an almost trapezoidal profile at the end. The blades are often laminated with various styles of tip. Kampílan blades often have holes near the tip that are sometimes filled with brass. Rarer still are specimens that have tips exhibiting a kris-like fretwork, while others have engravings down the entire blade. Although the kampílan can be used with one hand, it is primarily a two-handed sword. At times the hilt was bound to the hand by a talismanic piece of cloth to prevent slippage. Sometimes a chain mail covering was attached to prevent the hand from injury. Almost all kampílan originally had large metal staples protruding from the cross guard above the grip. Hilts were made of hardwood, but expensive examples that belonged to datus are covered in silver sheet or are entirely manufactured of expensive materials such as ivory or bone.
The laminated steel blade of the kampílan is single-edged, and made from an Arabic pattern-welding process and is easily identified by its tapered profile, narrowest near the hilt and gently widening until its truncated point. The blade's spikelet has led to the description of the kampílan in some documents as "dual-tipped" or "double-tipped".
Sheath or scabbard 
The scabbard is usually made of cheap wood and is bound with simple rattan or fibre lashings. When the sword needs to be used immediately, the sword bearer will simply strike with the sheathed sword and the blade will cut through the lashings, thereby effecting a quick, tactical strike without the need to unsheathe the sword.
Scabbards are unadorned and are often disposable when going into battle. Some scabbards were also made of bamboo or were made with a handle that allowed half of the scabbard to serve as a small shield.
The hilt is quite long in order to counterbalance the weight and length of the blade and is made of hardwood. As with the blade, the design of the hilt's profile is relatively consistent from blade to blade, combining to make the kampílan an effective combat weapon.
The complete tang of the kampílan disappears into a crossguard, which is often decoratively carved in an okir (geometric or flowing) pattern. The guard prevents the enemy's weapon from sliding all the way down the blade onto bearer's hand and also prevents the bearer's hand from sliding onto the blade while thrusting.
The most distinctive design element of the hilt is the Pommel, which is shaped to represent a creature's wide open mouth. The represented creature varies from sword to sword depending on the culture. Sometimes it is a real animal such as a monitor lizard or a crocodile, but more often the animal depicted is mythical, with the nāga and the bakonawa being popular designs. Some kampílan also have animal or human hair tassels attached to the hilt as a form of decoration.
The kampílan is a weapon used for warfare, used either in small skirmishes or large-scale encounters. According to Philippine historical documents, the kampílan was widely used by chieftains and warriors for battle and as a headhunting sword.
