Fully TPU balisong trainer. I made this from TPU rubber to make it super safe to play with or train with... the blade is flexible so it's even safe if kids play with it. It uses real pivot hardware to ensure longevity including washers for smoother action. The motion on this isn't going to be as perfect as say a PVC or aluminum trainer, but for a fully rubber trainer it's fun to play with. I would consider this more of a fidget toy for basic flipping.
