Introduction: Knex Grenade With Firing Pin

A simple yet effective grenade. It has a "door" in front, a hatch for putting ammo in (on the back), and a pin that is locked in place. This grenade is also very small and easy to build (perfect for beginners).

Step 1: Required Pieces

To make this grenade, you need:

Rods:
white: 3
Blue: 2
Yellow: 4

Connectors:
Grey, 1 slot: 3
Yellow, 5 slots: 6
White, 8 slots: 3

Misc.:
Black "Y" connector: 2
Black socket connector: 1
Tan connector: 2
Grey spacer: 1

Step 2: Building the Body

Yeah... pretty self-explanatory.

Step 3: Building the Door

Again... easy peasy.

Step 4: Building the Pin and Hinge

Yeah... easy.

Step 5: Building the Hatch

>_> need any more explanation?

Step 6: Putting It Together

Attach like so. The bottom of the door (the side without the gray connector) should just rest into the y connector on the body. When the door is in place, push the pin through until it clicks into the socket connector. (images 2 and 3 are different angles.)

Step 7: Loading the Grenade

You are finished! To load the grenade, push up the blue part of the door, insert green rods, and close the hatch. When you are ready to throw it, hold the grenade vertically in your right hand with the door facing away from you. Next, pull the pin slightly towards you, and then out. This will release the door. Finally, chuck it at your target. Have fun!

How does this explode? Rubberbands? Or does it just fall apart?

the most realistic grenade on this site, spoon, pin, and shrapnel 5*!

Yes it is a fantastic knex grenade, but no it does not have spoon but if you read my comment below you will see that i have made one with a spoon which flings off and when this happens it explodes (usually in mid air which is cool because you don't have to throw it at the horund)

author

the "door" is the spoon.

author
thomaswatton made it! (author)thomaswatton2009-09-01

Wel li guess you could call it "the spoon" but it isnt really a spoon is it. Google spoons on grenades and they won't look like that.

author
An Villain made it! (author)An Villain2009-09-01

it functions like a spoon, i don't care what it looks like.

author
thomaswatton made it! (author)thomaswatton2009-09-02

No it functions nothiing lyk a spoon it does not fling off it mearly falls off and a spoon does not release sharpnel when it comes off.

author
An Villain made it! (author)An Villain2009-09-02

it is close enough, this is a functional, realistic grenade, end of story.

author
thomaswatton made it! (author)thomaswatton2009-09-02

Start of story again lol, yes it probably is the most realistic grenade but no it is no where close to being a spoon, it is more of a hatch if anything.

author
An Villain made it! (author)An Villain2009-09-02

it is like a spoon, but it does not function like a spoon, you are right.

author
thomaswatton made it! (author)thomaswatton2009-09-03

I've just done a mod to this grenade wat i did was switch round a cuple of pices and add a spoon 2 the grenade and attached a few rubberbands to it. So now when u pull the pin out your hand is the only thing holding the spoon down so when u throw it the spoon flys off. This causes the hatch to be forced open and highly increases the blast raduis of the green rods. This also alows the grenade 2 blow up in mid air so it does not have to be thrown at the ground P.s sorry 4 the essay
