Benchmade Bali-Song butterfly knife

Benchmade Bali-Song butterfly knives with 108 mm blade length and gray steel handle

The butterfly knives, with their double-jointed handles, are part of the large family of folding blade knives. They are also available in different sizes with more futuristic designs for the greatest pleasure of knife collectors.
Butterfly knives, commonly called Balisong by collectors, are more than simple accessories. They were created for military use before becoming competition weapons for martial arts such as Kali-Eskrima. They are characterized by a sharp blade and a handle incorporating two movable branches that can be opened or closed with one hand. The sequence of opening and closing this handle is what allows for performing tricks. These are extreme figures that only professional knife handlers can execute. Folding blade knives are characterized by their blade that folds into the handle. But when it comes to butterfly knives, even though they are part of this category, they stand out because of their design. It's the two movable branches that will envelop the blade when it's not in use.
