Introduction: K'nex Balisong/Butterfly Knife
i know that the handles are not very stable, the smoothness of opening is not very good, and its very large. aside from that, this butterfly knife actually has a recognizable blade and handles that cover the blade (somewhat) when closed. plus, it even locks open.
and sorry for any blurriness.
Step 1: Blade
the broken 90* connector is not a design requirement, it was simply the piece i had available when i built this. a 45* could also be used in its place.
Step 2: Handle 1
once again sorry for the blurriness
the two pin clips are used to prevent overturning when opening
the piece between the two 90*'s is the female connector for a ball joint
Step 3: Handle 2
Step 4: Connecting
woohoo!! more blurriness!
connect the handles to the blade.
be careful to note the direction of the pin clips on handle 1.
