Karambit

Karambit is a working knife , which has its roots in the Indonesian archipelago. In the 11th century there are the first mentions of this type of knife. Even today, the crescent blade is used by fishermen and gardeners. The ring at the end of the handle helps to hold the knife when working with your hands, preventing it from falling out of your hand. Today, the knife is often used in Filipino martial arts, where the knife rotates around the pinky finger.
According to the inventors of these knives, the ancient Indonesians, the shape of the karambit is based on the curvature of the tiger's claw; the ancestor of these knives originated in this region sometime in the 11th century as a tool for farming, fishing and as an effective weapon. It is the crescent-shaped curve of the blade of these knives that makes them a much more versatile tool than a knife with a regular, fixed, straight blade. With the boom of trade in Southeast Asia, especially in the 19th century, these knives spread around the world, thanks largely to sailors, as a renowned and effective weapon suitable for both offense and defense.
