Knex Black Carbon Serated Knife





Introduction: Knex Black Carbon Serated Knife

This is my first ever Instructable so please give me advice and tips. (If you want to, I'm not forcing you)

Well I was just messing around with my knex when I noticed that when I put a silver spacer on top of a ball joint it looks kind of serated...

It's also good because it hardly uses any pieces.

After I'd messed around enough I came up with this, a black, carbon looking serated knife. Well here it is:

I'd also like to hear about any mods to it please

Step 1: The Pieces You Will Need:

Here are the pieces you need to make the whole knife:


17 green
10 white
1 grey
1 long flexible


2 orange (holds 2 rods)
4 grey (holds 2 rods)
3 red (holds 3 rods)
3 green (holds 4)
6 yellow (holds 5)


9 blue spacers
25 silver spacers
25 ball joints
23 ball joint connectors
3 little ball joint connectors

I think thats all of them...
Tell me if its wrong.

Step 2: The Blade

Easy - just look at the pictures.

Pic 1: Do this. Make 25 of them.
Pic 2: Make this.
Pic 3: Make this also
Pic 4: Put them together.
Pic 5: You have just made the blade.

Step 3: The Handle

Pic 1: Make 2 of these.
Pic 2: Make this.
Pic 3: Attach them together with 4 white rods.
Pic 4: You've just made the handle.

Step 4: Puting It All Together

Just snap them together really...

Once you've done please rate it :)

Oh yeah I'm not responsible for what you do with this knife.
(Not that you can hurt yourself with it anyway...)

    good idea to make a serated knife but looks a little wierd

    It is a little bendy but the silver spacers fit snugly over the ball joints, try it and you'll know what I mean

    i would try but i dont have enough silver spacers to make it. I dont know what happended to all the ones that i had but they are gone now.
