Gravity karambit

a crude recreation of the Reate Exo K. the mechanism just snap in to the closed or open position (unlike the real one that use push button lock). I use m3 x 10mm bolt. the 3D printed "nuts" is only for decorative purpose an can be tricky to put on. the snap action can be adjust by filing the blade, the A spot for closing snap and the B spot is for opening snap. by filing it, the snap action will be lighter. Make sure not to file it too much, It will open while you spinning it or it will not going to snap into position at all. I just making it out of curiosity. Not a great design, but I'm hoping someone can improve it especially on the looks.
