Each and every Armed Shark Balisong is hand-assembled and tested to ensure exceptional flipping performance. All our balisongs come with thread-locked screws. NOTE: This product is a Balisong Trainer, not a real knife. The "blade" shown in the pictures is a dull metal piece designed to mimic the weight and feel of a real blade. Balisong trainers are for recreational and educational purposes only, not weapons.
