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?

DUDE ITS NOT FREAKING ILLEGAL AS LONG AS U DONT USE IT AS A WEAPON ITS NOT BRO IVE SEEN ALL LAWS ITS NOT

It is illegal no matter how often you dispute it. It doesn't matter if the knife is homemade or factory made.

Possession, not only its use, is illegal.

You can review the relevant US law here:

There are _several_ laws prohibiting this in the UK, but I can't lay hands on them.

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.

so true man u feel me man

The website is INSTRUCTables NOT SHOWOFFables

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

I agree with jc industry

what kind of knife is it

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.

I now how to make it its easy really
instructions r not neaded its quite obvious how to make
get two pvc pipes one that can fit in the other
attach a knife to the tip of the smaller one
drill a hole in the smaller tube and in the larger tube so they wilk line up
put a spring in the bottom of the larger tube
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 "spring knife" 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,
but i'm pretty sure this counts as: song distens weapon
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 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
heydiddlediddle (author)  Johnhall442 years ago
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.
heydiddlediddle (author)  Johnhall442 years ago
That's what I use...
7.62x54r, try it sometime. Its magical =P
heydiddlediddle (author)  Johnhall442 years ago
lawlz
You can even hunt planes with that ammo.
