Butterfly Knife
A butterfly knife, also known as a balisong, fan knife, or Batangas knife, is a type of folding pocketknife that originated in the Philippines. It is characterized by two handles counter-rotating around the tang, concealing the blade when closed. The distinct features of a butterfly knife include:
- Two handles counter-rotating around the tang
- Unsharpened spine of the blade
- Tang and tang pins
- Zen pins
The origin of the butterfly knife is debated, with some believing it originated in the Philippines around 800 AD, while others suggest it was introduced to the Philippines by the French in the late 1800s. The knife was initially used as a self-defense weapon and a common pocket utility blade. Over the years, it has gained popularity in martial arts and has been featured in various martial arts movies.
In terms of legality, the status of butterfly knives varies by location. For example, in Hawaii, it was illegal to possess, manufacture, sell, transfer, or transport any balisong/Butterfly-type knife, but the ban was overturned by the 9th Circuit Court of Appeals in August 2023. In Kansas, the carrying of all types of bladed weapons was decriminalized as of July 2013. In Illinois, it is legal to own and carry a butterfly knife.
In summary, a butterfly knife is a unique folding pocketknife with a rich history and cultural significance, particularly in the Philippines and martial arts communities.
