This knife is part of a series of weapons for BATTLEFIELD 2142, the Morretti SR-4 is part of that group. This weapon can easily be used to humiliate any foe.

In step 3 part 1 you can replace the 3 upper yellow half moons with white snowflakes, by doing this you can turn it into a bayonet!

Step 1: Parts

Gather the parts that are needed:

Green Rods : 20
White Rods : 21
Grey Rods : 2

Dark Grey Connectors : 3
Red Connectors : 5
Green Connectors : 2
Yellow Connectors : 11
White Connectors : 2
Y Connectors : 1
Tan Clip Connectors : 1

Step 2: Start to Assemble the Parts

1. First of all make this part.
2. Add a red connector.
3. Add a yellow connector and a green rod.
4. Add another red connector.
5. Add 2 white rods.
6. Add a third white rod.

Step 3: Continue to Assemble the Parts

1. Add 4 Yellow Connectors, 3 White Rods and 4 Green Rods.
2. Get your 'Y' Connector ready.
3. Attach the 'Y' Connector.
4. Attach the 2 Grey Rods.
5. Make up the knife tip using a Dark Grey Connector, A Green Connector and a Green Rod.
6. Attach the tip to the Grey Rods.

Step 4: Assemble the Handle

1. Add a Connector and a Green Rod on each side.
2. Attach a White Rod across the handle and then attach 2 Yellow Connectors and 2 Green Rods, Repeat on the other side.
3. To one side attach this to it.
4. Attach 2 White Rods.
5. Add a Tan Clip Connector
6. Repeat Step 3 and make sure that the White Rods from Step 4 are connected.

Step 5: The Final Checks

1. Check the handle and make sure it is all put together correctly.
2. Make sure the blade is correctly connected into the handle.

Step 6: Complete

The knife is now complete. This knife is good for combat training, to do this cover the bottom Grey Rod and the tip with your mum's or your sister's lipstick. And when you you get a critical hit like the neck you will know for sure.
<p>Most combat knives are non-folding and have a full tang in order to be sturdy, as they have tou double as survival and utility knives. Folding knives are good for EDC (Every Day Carry) as they are lightweight and small, so they are very portable and practical, but can't withstand a lott of force since the hinge is the weakest part (even if it is reinforced, it's a Solids Mechanics principle). But in a situation that requires my life depinding on a knife, I'll take a full tang 1/4 inch thick knife anyday over a folding knife. Moving parts = less cross-section inn that point = effort concentrator in the material = point of rupture. </p>
Does it fold?
combat knifes don't fold i like your knife a little better. this knife looks cool though.
Some combat knives fold.
yep. that's true
Most combat knives don't fold as if you went to slit someone throat you would have to open it, giving your position away with the distinctive "ching" of the knife springing out, unlike a solid one with a leather sheath!
1. Unless you are a terrorist you shouldn't do that. 2. Can't you open it quietly. 3. it is safer to have a folding one than stabbing your OWN leg when its in you pocket, and that's just pathetic. 3. What was the point of typing all of that I hate when i type that much.
Lol, you imply that only terrorists use knives. Why do you think it's called a &quot;combat&quot; knife? Also, you used the number 3 twice.
fail with the 3s there :L a combat knife could also be used as a bayonet or vice versa
True. But still, it was <em>designed</em> to kill.
can you make a holder?<br>
WOW MAN YOUR GREAT! PLEASE MAKE MORE VIDS!!!! :) PS LOL LIKE TH LIPSTICK IDEA
You sound intelligent. Please, tell me more.
great game add me carbine98
I ,EAN MORE MODULES
amazing if you make it, you have to have sumdude's knife mod and mango man's knife sling so u can put it ind a holster
will it break if you actually try to stab someone?
Mine doesn't break. I don't know about the original, though. my mods: Add 22 orange connectors between the grey rods. Add some blue spacers on the lower rod (looking at the first picture in step 6) in front of the orange connectors. Change the red connector on the left (still on the same picture) with green connectors, and connect the extra slot with a white rod. And put a few more rods through the handle (particularly where the yellow connectors are. I've tried throwing mine against the wall, and it stays intact.
The original did survive if you "stabbed" someone
Yea, it would probably break off only the few connectors at the tip just like the modified one.
nice
unfortunate name hehe
I modified this to look more like the real thing. It is less structurally sound though. See?
ye..not as strong in the handle
Mmhmm, was weakest at the blade connection to the handle.
A NOTE TO ALL: I WILL NOT BE MAKING WEAPONS FOR A WHILE, DUE TO MY REAL AND MOCK GCSE EXAMS. I WILL POST PLANS FOR SOME STORAGE DEVICES (CUPBOARDS...ETC), AS I BE WILL DOING THESE FOR MY GCSE TECHNOLOGY COURSE. MY FIRST ONE SHOULD BE AVAILABLE IN THE 1ST QUARTER OF 2009, BUT I WOULD NOT COUNT ON IT. OTHERWISE I WILL ONLY CREATE WEAPONS IN MY HOLIDAYS, WHEN I USUALLY SIT AROUND DOODLING ON PIECES OF PAPER, THEN SEEING IF THEY WORK...THATS WHAT HAPPENED WITH THE AK-47 AND THE LEE-ENFIELD LAST YEAR. IF ANYBODY HAS IDEAS FOR WEAPONS - PLEASE POST YOUR IDEAS HERE IDEAS I AM CONSIDERING ARE: P90, M40A3, MP44, MP40, SPRINGFIELD, WALTHER P-38, BAR, BROWNING .50 (MADE ONE - USED 80 LITRES OF KNEX - I HAVE AN 80 LITRES TUB FULL OF KNEX)
I have more time than I thought!
A NOTE TO GUN MANIAC: WHY DO YOU USE CAPS?
keyboard on old pc was bust, fixed it now :)
I agree with Neo1, looks cool, I think more knives/swords/other close range weapons (Not Guns, we got enough of em' anyways) is just what the K'nex Community needs!
ye, and mines and grenades
is the lee enfield made yet?
It was, i was going 2 post a vid... i loaded it, went 2 fire a knex rod, it jammed and blew itself apart. So im working on a version that fires bb's instead.
I really like this knife, Gun Maniac!
Thanks, my next weapon, if I can be bothered to make is hopefully an ak47, with hopefully a full auto firing system or a lee enfield rifle with a bolt action loading and a 5 round magazine.
i made something similar more of a modern combat knife
I'm not really sure if that would be 'modern'. Modern combat knives still have the type of handle you see in the BJ-2 (which, ironically, is in the future). The yellow rods on the handle don't look too strong, and it looks like the center of gravity of the knife is towards the front. But nice work. Now if only we could have a knife fight...
it is very strong and the center of gravity is near the middle
Nicely done. I built it and placed 22 orange connectors between the two gray rods, along with a few blue spacers. It's heavier, but the center of gravity is near the white connector (and it's stronger).
Good Idea, I did that at Christmas and made 4 knives so me and my mate can "knife fight", and a left a 2 inch gash on his arm because a few of my orange connectors have a sharp edge.
I finished my instructable for the modifications.<br/><a rel="nofollow" href="https://www.instructables.com/id/Knex-BJ-2-Combat-Knife-mods/">Here.</a><br/>
Do you connect the y connector to the bottom grey rod?
You could, but if you snap a white rod in the yellow connector instead (and connect it to the white connectors) it adds sturdiness.
I've just learned to use Google Sketchup, and I've begun to model my mods to this knife. Just asking permission, may I refer to this instructable in my own?
Has Anybody Seen My Knife?!?!?!?!?!?!?!?!?!?!?!?
i just got a knife called the firefighter and it IS SHARP!so any ways cool instructable :)
Try to make a k'nex replica of it. But post some pics of it first...
k. OH but its going to be shiped from floridia soon i hope but i did get a cool red9 airsoft!!! :D
Well then post pics of it <em>when</em> you get it and we'll see how it looks.<br/>
looks good
