Butterfly Knives

Butterfly knives, also known as balisongs, are folding knives that have two handles that pivot around the blade, allowing the knife to be opened and closed. When the knife is closed, the blade is concealed within the handles, and when it is opened, the handles flip out and lock into place, revealing the blade. Butterfly knives are also sometimes called fan knives or Batangas knives, and they have a long history dating back to the Philippines, where they were originally used as a tool for hunting and farming.

Butterfly knives are known for their fast and smooth operation, and they are often used for tricks and stunts, such as flipping and twirling the knife. However, butterfly knives can also be used for practical purposes, such as cutting rope or preparing food.
