Filipinos have been accumulating knowledge and developing technology from ancient times, from naval science, traditional shipbuilding technology, textile techniques, architectural food, indigenous arts, and techniques, to culture, science, and contribution from Philippine people — both ancient and modern times.
Cannabis
Cannabis is a large curved sword in the south of the Philippines used by several ethnic groups. It ranged between 2 and 4 feet in length and was handled either with one hand or with both. It was used as a fighting weapon, as a power-showing instrument. There has also been occasional use as a farming and butchering tool. The name of the sword is a shortening of the word 'pang-tabs,.' The root word tables are, therefore, their etymological origin.
Kudyapi
The Kudyapi is a two-string, stirred boat lute from the Philippines. It's the only stringed tool among the Visayas and Mindanao people and one of several other groups, like the Manobo and Maranao. It's four to six feet long and has nine beeswax frets. The tool is made of solid softwood like the jackfruit tree. The kudyapi was found among the groups like Visayans, the prevalence of which is and/or is found in other parts of the Philippines, just like kubing or other musical instruments.
Balangay
Balangay was South East Asia's first-ever marine wooden ship. It is also known as the Butuan boat, as nine specimens of these boats were found in 1976 in Butuan, Mindanao, from pre-Hispanic times, the earliest in 320 CE. The Austronesians are believed to have migrated on the Balance to the Philippines. When the first Spaniards arrived in the 16th century, the Philippines lived in well-organized independent, Baranggáy villages. The name Barangay was derived from Balangay, the word Austronesian for "sailboat."
Gandingan
Gandingan is a set of four large, hanging gongs from the Philippines used in their kulintang set by the Maguindanao. It works as a secondary melodic instrument after the main melodic instrument, the kulintang, when integrated into the ensemble. The gandingan can communicate with each other by playing solo, enabling them to send long distances of messages or warnings. The gandingan connotation was this ability to mimic the tones of the language of Maguindanao using this instrument: the "talking gongs."
Kalis
The Kalis is a type of Philippine double-edged sword that often has a keris-like "wavy" section. Like the Keris, it can be used for cutting and sprinkling the double-edged blade of Kalis, except that Kalis is much larger than most Kerises and is a sword rather than a dagger. The wavy part of a kali is said to make it easier to fight – as a straight edge tends to stick in the bones of the opposite person, the wavey portion makes it easier for the Kalis carrier to remove the weapon out of the body of his opponent.
