Also known as a fan knife and in the Philippines as the balisong, this butterfly takes the cake. First off you immediately notice the blade witch comes really sharp. The silver blade is made from stainless steel with a drop point blade. The handle is also stainless steel with a steel frame and decorative mounts. Double walled and held in place with screws this knife is durable with a heavy duty construction. At the end of the handle is a securing latch. When you are finished showing off your mad flipping skills fold the blade inside the handle and close it up tight.
