About this 3D model

(Edit) V2 has a thinner blade for those experiencing friction between the blade and the handle on their prints. Does not affect tolerance at mounting point for continued tight operation. Simple Heavy Trainer for practicing butterfly knife operation. Heavy weight allows for great practice. Easy assembly and disassembly for modification and interchangeability. Over-Engineered for your enjoyment. Already have many other models based on the same design, that will have interchangeable parts with this model. I ask that by this CC license that this model is not copied, reproduced, or modified, in order to keep this model free.
