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.
12 green rods
10 white rods
2 yellow flexi rods
7 yellow connectors
1 white connector
4 red connector
3 light gray connector
1 gray clip
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)
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.
