The History And Evolution Of Butterfly Knives

Butterfly knives, also known as Balisongs, are a type of folding knife that originated in the Philippines. These knives have two handles that rotate around the blade, allowing them to be easily concealed and carried. The design evolution of butterfly knives can be traced back to ancient Filipino weapons called Batangas knives, which were used for self-defense and hunting.

Over time, Batangas knives evolved into what we now know as butterfly knives. In the early 1900s, American soldiers stationed in the Philippines brought these unique knives back home with them, where they gained popularity among collectors and enthusiasts. Today, butterfly knives are popular not only in their country of origin but all over the world.
