Introduction: Knex Locking Switchblade Knife

Picture of 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:


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)

ruber band

Step 1: Build All Parts

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