The longest sword native to our country, the Kampilan. Typically 85-100 centimeters long (I suck at numbers so don't ask me to convert to inches), this baby can slice a man in half with a good swing. Maguindanao and Maranao Warriors prefer this weapon, which is a good choice since it is powerful and decisive.

The long and ornate hilt counterbalances the long blade, which is good. Like twirling a rattan stick, its easier to twirl a stick held near the middle, than one held near the base. The ornate hilt at times make it difficult to handle the sword, so a certain level of expertise is required when using this on battles.
Datu Lapu-lapu is thought to have used this sword in his battles as depicted in his many statues and paintings. Cool.
