This Butterfly Practice Knife is an excellent choice if you're thinking about entering the fascinating world of knife tricks and flips. It showcases a completely safe and unsharpened, 9.5 cm 5Cr13Mov stainless steel blade which is connected to the 10.5 cm steel blade through a sandwich construction. The main reason why this trainer is a popular choice among beginners is the skeletonized design, which results in weight reduction. This contributes to better balance and control, especially when you're just getting to know the knife and how it moves in your hands. It also features a safety lock for keeping the blades closed and easier carry.
