Knex Hidden Blade

This is my first Instructable so it may have problems, it may not, I don't know.

Knex Hidden Blade from Assassin's Creed. I only used basic pieces with minor/optional modifications. I also used string for the trigger and rubber bands to move the 'blade.' Taping the bottom of it is optional and makes it more comfortable in my opinion.

Step 1: Parts

For most things you build from the other instructions on here, most require a lot of pieces. This doesn't require many at all. You need:

Rods:
2 Red Rods
1 Grey(Black) Rod----*I do not know how it will work with a grey rod. The black rod is stronger.*

Optional Rods:
1-2 Green Rods---*These can be used on the locks to stop them from spinning completely around.

Connectors:
7 Orange Connectors
15 Grey Single Connectors---*Some are optional, just used to hold the rubber bands*

Spacers:
3 Small Blue Spacers
3 Larger Grey spacers----*Grey spacer = 3 small blue and they can be substituted*

Other:
2 Rubber Bands
String---*Length Varies from person to person*

Optional:
Tape for comfort

I'm planning on trying to make one out of metal or some other material that is more durable and more realistic. If anyone has any ideas that may help or suggestions, please let me know. Thanks.

Change how the rubber bands are attached. I built this blade and it cut my arm in three spots.

[Delta960]

really? I've never had that problem. I'll look into alternative ways to set it up.

So here's my version of the whole hidden weapon thing ... fires 20-30 ft shell ejection and is able to be concealed check it out!

i a a little confused on how to rubber bands satay on the rod when it is armed and exacy how the rod isint thorwn when u load it and  fire could you please help

[Delta960]

I am trying to come up with a better way, bu the only way they stay on the rod is a little notch I made at the end of the rod. The rod doesn't shoot out because i have the gray locks that are snapped onto the "blade" rod. This makes it so when the rod slides out, the gray piece stops it from actually coming out. Hope it helps you out

[waffles305]

how does that work im tring to make 1 just without knex

[Delta960]

i'm not sure if this will answer your question but:
When the rod is pulled back and the rubber bands are tights, and you release the lock letting the rod through all the way. The rubber bands pretty much throw the piece through the pieces and the other lock keeps it in place.

Nice work man, 5/5. I Will build it today. And subscribed :)

[Delta960]

Thanks, I'm still trying to improve it, so if you find anything I can change or add, let me know

[deaniscoolproductions]

hey man i rated it a 5 star ,and subscribed ,wow thats an awsome idea, i like it and it quite fun to play with ...im coming up with new ideas for you but im not quite sure yet but when i figure them out ill telll you so you can update it to make it better :) thx man awsome design

[Delta960]

No problem, lol. You are right for sure, it is very fun to play with. I have one for each hand so I'm duel wielding hidden blades like in the New Assassin's Creed coming out, lol. My only complaint against my own design is the rubber bands wear out and become too weak.

[coolo52]

you could sand the edges of the black piece to make it look like a blade

[Delta960]

I have done that, you have to watch doing that because by sanding the blade piece too much, the lock system i have won't stop the piece so i just kept it with the unsharpened tip to avoid that
