Intro: How to Make a Balisong (Butterfly Knife)

People, I first want to tell you that due to the fact that these weapons contain very few design flaws, the International police have made it illegal in almost every country; Including Australia, the U.K. and America. So I'm putting this on in case you find that you may require one (to get back at buggers, keep bullies at bay etc.). but nonetheless: Ladies and Gentlemen! Boys and Girls! I present to you the Epitome in weapons; the Butterfly knife!

P.S. First, don't whine to me if somebody gets hurt or killed with my product. you killed 'em so it's your fault.
second, no whining to me to remove them, they're legal in lots of countries and if you're not happy with that; go and join your emo convent. its ok if you just tell me that its illegal in your country ( IF YOUR NICE ILL GIVE YOU SOME TIPS ON HOW TO KEEP IT.).

P.P.S. any suggestions are fully welcome and encouraged. I would love to see the community get creative (even if it is by exploiting one of the most dangerous weapons ever).

STEP 1: Making the Handle, Basic Outline

To make the handle is to doe the hardest bit. Since this weapon is custom, measure your hands and cut two half-handles appropriate to said size plus 5 mm or a bit more.

STEP 2: Handle, Rounding and Blade Holding Drill

next step is to sand the top edge so that they will rotate in the main shaft easily (without colliding). Don't do too much or it can screw the design a bit.


Since that last step was short I'm putting the next one in here as well; in sanding the top you should have created a semicircle (more or less). Halfway through the semicircle drill a 5.5 mm hole.

STEP 3: Blade Rotation Rut

Next we will create a 1-2 mm rut a the top of the shaft to allow the blade to rotate. let it be around 2 to 2.5 cm. cut it straight in the middle on the opposite sides to the holes you drilled earlier.

STEP 4: The Blade

now to make a blade! at long last! I made my blade tan-to style (a tanto is a ninja knife) but feel free to improvise! make lapu lapu swords, combat knives, goreswords and even small keys! so first part is to make the rotation piece. make sure this fits with your handles so that they can go 180 degrees. then you can make the blade. it must be smaller than the handles of course.

STEP 5: Containment Rut

this is the unique thing that inspired the "switchblade" style knife. the containment rut is in both handles and is used to hold the handle.

Make the rut halfway through the handle to be safe or more if nessescary, both the handles must conceal the blade completely.

STEP 6: Putting It Together

finally! use simple 5 mm nuts and bolts to attach the blade to the handles. be sure they are tight!

STEP 7: The Greatest Assasin Weapon of All Time!

Congratulations! you have just created a Balisong butterfly knife, the most concealable and best assasin weapon known.

Where the hell did you get this idea about "real" knives? butterly knives are illegal to carry, PERIOD. The cop isn't going to care if you say "oh, I made it myself."

No. They. Aren’t. This. Law. Applies. Differently. In. Each. State.

No joke! And what in the world is a "real" knife? If it has a blade, and can cut, it's a knife. Doesn't even have to be metal. Ceramic and even rocks can be made into knives. Whether or not you made it has nothing to do with the legality. Check the laws before you spout your words of wisdom to the impressionable masses.

 chill out mate. love don't hate.

Anywho, I apologise for my previous comment, they are correct, a knife is a knife no mater how dispropotionately-shaped/sized it is.

um, actually, idk bout anywhere else but in illinois the law is any, ANY (cept switch bladdes), knife that has a blade shorted than 3 inches is completely legal um, i'd make it first then ask him so that if he says no you'd already have it made

Yeah, and steal the car and hit the town too. They can't stop you if you ask after you've done it. (insert sarcasm here)

Are these knifes legal in Australia?

freddysserpent 12 years ago

Balisong knives are illegal but a bali-sword is not (a knife is considered to have a blade lengh of less than 15" according to customs)

SgtJellyfish 12 years ago
