The Benchmade 550 Griptilian Trainer is a non-sharpened knife that allow for the safe practice of self defense, martial arts, and training scenarios. The trainer lets the user learn and deployment techniques, perform drills, and develop confidence and muscle memory without risking cutting themselves or others with a sharp blade. The 550 Griptilian Trainer is identical in weight and size to the 'live' model. To enhance the balance of the piece Benchmade blunted the unsharpened tip and drilled holes through the blade, removing unnecessary bulk. The familiar Griptilian texturing on both sides of the handle allow easy multi-directional grips during training. The Benchmade 550 Griptilian training model has a red handle designating it as non-sharpened.
