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.
done  =:^b
<p>i made a smaller version that is also a karambit</p>
<p>The degrees symbol isn't right. If you have used the Alt key, then do this: Alt+0 . You will come up with this: &ordm; . Hope this is some advice. =:^D</p>
Can this do tricks like a real butterfly knife, or is it just switch blade. Because im looking for a knex ballisong to practice with so i wont cut my self with the real thing
this one is kinda flimsy for trying tricks but i do have a reverse ballisong tht would be ok for tricks, also you can get practice butterfly knives or for a cheaper alternative put a strip of electrical tape up the blade to cover the edge. hope this helps =:^b<br>https://www.instructables.com/id/Reverse-Balisong-Knex-Knife/
