Your average butterfly knife. Source
The butterfly knife, also known as a balisong
, is a traditional Filipino knife. Its design, with two rotating handles, allow it to be flipped open and closed
. It will usually appear in the hands of a Knife Nut
, who will perform a complex, flashy and noisy
flip. Anything beyond a simple and quick opening is Awesome, but Impractical
as the hand is vulnerable to a strike disarm throughout the manipulation. Less frequently, a character will flip one open without fanfare and use it to cut something
The most common and recognizable design is skeletonized: holes in a line along each handle. The holes control balance and add grip. Traditional balisongs incorporate wood into their handles with brass accents.
Not to be confused with butterfly swords
, which are single-edged short-swords that are dual-wielded
and used in Chinese Kung Fu.
