Hey, guys. This is an easy PVC ballistic knife I made recently. I won't be telling you how to make it, that's a trade secret, but you might be able to do it from the pictures. I used a trumpet valve spring in the demonstration picture, but I usually use a spring from an airsoft gun. Tell me what you think!
That is 100% illegal in the u.s. and the uk dont listen to people saying its not a ballistic knife propelled by a spring carries a minimum of 5 years in prison for possesion or sale a explosive proppelled ballistic knife however isnt illegal but is very restricted under the aow (all other weapon) category so if I were you I would take it appart and never build it again. Yes its cool but is it worth 5 years in prison?
<p>It is illegal no matter how often you dispute it. It doesn't matter if the knife is homemade or factory made.</p><p>Possession, not only its use, is illegal.</p><p>You can review the relevant US law here: </p><p><a href="http://codes.lp.findlaw.com/uscode/15/29/1245" rel="nofollow">http://codes.lp.findlaw.com/uscode/15/29/1245</a></p><p>There are _several_ laws prohibiting this in the UK, but I can't lay hands on them.</p>
What size of PVC is it
It's awesome, ignore the hate bruh
It's a pvc tube cap end dowel nail spring and pin made from a bolt on the end of a clip. Spring in back end of tube glued into cap end nail&quot;knife&quot; in front end of dowel compress spring put pin in hole in dowel to lock it. Point press clip. Dowel shoots out. Smoke ace go make it.
That's actually illegal
<p>no it isn't</p>
<p>In the USA a spring powered ballistic knofe is illegal </p>
<p>hey greasy american did he say he lived in the USA not everyone is a greasy basement dweller like yourself MCDONALDS for life </p>
<p>very illegal </p>
<p>no it isnt stupid just dont build it</p>
<p>Ok now everyone's saying that this is illegal but I mean come on people this thing is AWESOME PERIOD. So if you don't like it then don't make it. Saying it's illegal aint gonna keep us people from making awesome things like cannons and swords that are funnily more approved than a small little knife that fits in your pocket also known as a pocket knife witch is also illegal for me to carry but I still do. So unless someone takes it from me it's mine buddy. </p>
<p>so true man u feel me man</p>
The website is INSTRUCTables NOT SHOWOFFables
<p>The website is called INSTRUCTables, don't be all hey look what i made isn't this cool? I'm not going to tell you how to make it though</p>
I agree with jc industry
<p>what kind of knife is it</p>
Please add instructions or at least send instructions to me
I don't think instructions are a good idea...
That's awesome
Maybe a separate app called 'Idea'ables is needed then instead of Instruct! As in instructions!!
Screw everyone cracking on you. Nice ballistic knife.
Hope ya don't get caught with that, FBI watch lists don't just go away.
I now how to make it its easy really
instructions r not neaded its quite obvious how to make<br/>get two pvc pipes one that can fit in the other<br/>attach a knife to the tip of the smaller one <br/>drill a hole in the smaller tube and in the larger tube so they wilk line up<br/>put a spring in the bottom of the larger tube<br/>attach something to the tope of the large tube like a pin to fit thru the hole in latger tube and smaller tube so when u pull it out the spring will push the small one out
It's not a 'trade secret' to tell us how to make it, it's an 'instructable.'
Instructions pleeeeeeez!!!
really cool, but under my understanding ballistic is in relation to explosives, i read the law it says this classifies as a ballistic knife. In my opinion this should be a &quot;spring knife&quot; a ballistic knife should be related to an explosive like a percussion cap (from bullets or Hilti shots) despite the definition saying any knife that is a projectile not propelled by explosives. Lastly the law does say its illegal to manufacture, sell, possess or import a ballistic knife. I'm happy b/c their not illegal in Canada :D
this is really insane, sorry for saying it, <br>but i'm pretty sure this counts as: song distens weapon <br>and just not under fire weapon, but if i was you, look out next time, with posting stuff
It aint illegal, so I aint worried.
Nice simple design, it would be easy to copy. Just&nbsp;add to add a small model rocket motor, flip out stabilization fins and a titanium alloy for the trigger mech then you can hunt deer =P
Yeah... pretty sure that's not legal. Stick with a 30-30.
Lol, it counts as a pocket knife/model rocket =P 30-30 is overpowered for deer.
That's what I use...
7.62x54r, try it sometime. Its magical =P
You can even hunt planes with that ammo.
I would love to get shot by that!!! <br>lol
Cool. How heavy Is the knife assembly (not including the handle)?
It's really light (until you fill it with solder, that is!). It's really just the pvc and a knife blade super glued together (with a nerf dart as a spacer). If you want a more technical response, I do have a metric scale somewhere...
Sorry guys, I'm not posting because this is a very dangerous weapon and I don't want to chance a serial killer seeing this and thinking what a good idea it is. This thing will easily penetrate two inches of drywall with an airsoft spring installed. You can use it to dispense chapstick too, BTW.
Just because you don't post the instructions isn't going to keep a serial killer from killing somebody if they really want to. And besides there are much easier ways of hurting people.
True. I just needed a good excuse other than being to lazy too post it.
Isn't the point of this site to share instructions on how to make something? So if you aren't going to share the instructions, why bother posting?
No, this site is also for sharing ideas. That's why they have a slideshow option for instructables. Not necessarily just posting instructions.
How far does it shoot?
