Here's a video of I believe the world's smallest ballistic knife !
It took me about 6 hours to make this little thing, it is 6.5 cm long when loaded maybe it is short but it packs a punch when you shoot it :P.
I can carry this ballistic knife pretty much anywhere without anyone noticing.
Max distance with great accuracy: 2 ft
Length: 6.5 cm ( 2.5 '' )
Spring: 5 cm '' i took the spring from an ordinary lighter ''
I will maybe make a tutorial for it because I had to use a great amount of tools and skills to make this ballistic knife, if i find a faster and easier way to make one and have enough requests of making a how to i will make one :)
If you have a weapon, how to idea or a new invention you want me to make you can send me a email or private message of what you want me to do, i'll make it and a video of it.
