Intro: Knex Locking Switchblade Knife

This is a mod for Knex Switchblade by Mykhailo. His knife didn't stay shut without you having to hold the blade. Well I fixed that. Now all you have to do to open is push a button and give a flick of the wrist.

This should be easy enough so just follow the pictures.

Parts list:


Rods

12 green rods
10 white rods
2 yellow flexi rods

Connectors


7 yellow connectors
1 white connector
4 red connector
3 light gray connector
1 gray clip

Misc...

Black & Blue hinge (you don't have to use Black & Blue hinge you can use a red connector but I prefer to use the black & Blue)

Yellow rod clip thing ( you can use a tan clip but this works better)

ruber band

STEP 1: Build All Parts

Pic 1: build (this is going to be the blade)

Pic 2: build (this is going to be the body)

Pic 3: build (this is going to be the button) sorry it's blurry

STEP 2: Put Together

Pic 1-2: Add black and blue hinge

Pic 3: Add blade

Pic 4-5: Add side cover

Pic 6-7: Add button

STEP 3: Add Ruber Band

Add ruber band as in pic. Fold up knife and put the gray clip (that is on the button) under the light gray connector.

If you don't understand anything let me know.

the "yellow rod clip thing" is actually a gold track splice piece.
