Introduction: Reverse Balisong K'nex Knife

Picture of Reverse Balisong K'nex Knife

one of my favorites due to its density when closed and stability when open.

Step 1: Blade

Step 2: Handle

build two of these

Step 3: Tang and Pivots

this is where the blade and handles join together.

sorry for the blurriness.

Step 4: Connecting

Picture of Connecting

join the handles to the gray clips by the blue rod

the second connection of the half moon connector should be notched onto the small green (in this case black) rod

and finished  =:^b

can you tell me how to make an other blade instead off the one showen

you can do a drop point blade

The Sensei (author)IRISH_DC_952010-10-24

well, for this knife there i havnt found any way else to make the blade so tht it will be sturdy and still b semi-accurate to the real thing. but i do have a few other 'ibles of knex knives

i hope this helps =:^b

I think it looks a little bit big...but rly I don't care about size.

The Sensei (author)Knexfreak91232011-02-05

well i try to make all my designs functional and stable first and worry about size second, plus im 6'4" so its kinda the right size for me. and this is off topic but ur comment was such a good set up; thts wat she said! lol

Very cool!

instruct39 (author)2011-02-12

are these actually real or did you design it yourself?

The Sensei (author)instruct392011-02-13

there are actual knives like this, i personally like them better than traditional balisongs (butterfly knives)

jconway777 (author)2010-12-03

Does this knife require any special pieces? such as sharpend knex, rubber bands,ect.

The Sensei (author)jconway7772010-12-03

nope, its all regular, non-modified peices

~Aeronous~ (author)2010-10-07
