For Project: Butterfly Knife Trainer
#26 Enhanced butterfly knife by Bogdan Andrei
The main issue with the butterfly knives consist in poor bushing on the loint. Because the way the blade and the handles works, during extensive usage, these bushing get a significant gap which make the knife unstable and noisy.
In my design, the bushing are doubled as shown in pdf, and more important, because of the tethed sector on each handle, the "wings" (aka handles) work in total synchronization.
It maybe possible that this feature to not be desirable for advanced users, but for training is more than useful for sure
