Introduction: Knex Switchblade (Now Improved)

This is my knex switchblade. It was inspired by J_SCAP's butterfly knife. I decided I would make a switchblade, so it would lock in the open position or lock in the closed position (well, sort of), as the video shows (I hope you can view it). Hope you enjoy! Post pictures or videos if you build it!

This can also be used for self defense training if you add some of your sister's lipstick to the edges, that way you know if you have been cut and if it was a puncture or a slash. Although if you have the money, you should probably buy an actual rubber knife.

NOTICE: Yes, you can make a comment that actually has nothing in it. Just because Mepain and I did it two years ago does not mean you can spam up my instructable.

Step 1: Materials

This is all you will need. Exactly. I know this because I took apart the knife and rebuilt it from memory.

Step 2: The Frame

This will become the frame of the knife.

Picture 1: Build these.
Picture 2: Mutila... I mean "Enhance" a grey connector.
Picture 3: Attach it here.
Picture 4: Attach a red connector here.

Save the other part of the frame for the next step.

Step 3: The Blade

This is the blade very simple.

Picture 1: Build.
Picture 2: Attach it here.
Picture 3: Attach the other half or the frame.

Now you will need a rubber band for the next step.

Step 4: Bands

Attach a rubber band as shown in the pictures. The "improved" version (last three pics) can flip open much easier, but can't be flipped closed. I like flippy stuff. I have flippy pens, combs, knives, knex knives, pocket knives, and more!

It's fine if u have no bendys. I feel your pain. There are many knex pieces I never heard of!

w8.. does it lock down in place by its own

I built this knife a while ago, but pulled it outta a toy pile today, I modded it to have a switch, works great, would recommend it to anyone considering making this knife.

Very nice. Good job.

Thanks! It wasn't hard, I just thought it would be nice to open it easier.

Yeah. The problem when I was designing it was that I was trying to have an auto-opening style blade instead of an assisted-opening blade. Now I can see that assisted opening is better.

Yay for community help! POWER TO THE PEOPLE!!!!

sorry hailo said that darth acexxacer to tell him kinda what it means you where abiut so say mutalate but said enhanced...

No, seriously. I can't tell what you are saying. Use some punctuation, use some spell check, and actually spell out my name. It's not that hard, stopanator.
