Design can be improved to use two 3 long no friction pins for the handles instead of the whole axle thing also thanks for this. I made this a month ago and I’m hooked on the idea of learning balisong tricks with it
I also made a Lego balisong, but my design was slightly different. Instead of the x cross sticks, I really don't know the word, I used the loose circular ones, and a T shaped technic thing to keep the blade from moving.
