Practice Balisong/Butterfly Knife
thingiverse
A easy to assemble training butterfly knife. I measured the size so that it should fit nicely in your hand or pocket. The assembly is extremely basic, and all you need are 2 screws and hex nuts (whatever screws you have lying around will do) and a tool to cut them to the right size. Just screw the parts together (see photos for reference), PUT SOME SUPER GLUE ON THE HEX NUTS TO HOLD THEM IN PLACE, and you are ready to go. I only included one handle in the STL file so print it twice or duplicate in slicer.
