Training balisong knife GrandWay K01 A is a qualitative model that allows you to train in flipping and practice other tricks by manipulating this type of butterfly knife. This knife does not have a blade and its role is played by a plate with holes that carry both a decorative and a practical function to lighten the weight. As in the classic balisong this perforated blade folds and hides inside a stainless steel black handle. K06 A model has a skeletonized handle design divided into two parts and includes a durable tail latch for holding the knife open, or securely locking it closed. Such butterflies are not too heavy, feel great in hands and would not slip. This trainer tool is a guarantee of absolute safety training both for you and others as dull-edged blade is unsharpened to prevent cuts, hurts or any bruises. You get the following main advantages of flipping trainings: 1.It is an excellent training tool to practice tricks and manipulate with a real balisong and work up from beginners to advanced. 2. Reliable design - since there are no buttons, springs, and even more complex mechanisms, then there is nothing to go wrong, get mud and finally break down. 3. Even if you manage to improperly fold the blade or somehow put yourself in danger, nothing terrible will happen: the rounded and unsharpened plate is completely safe.
