    if ur gunna shrpn it so that it kils smbody, why not jst use the exatco nife?

    Why make a plastic knife when you have a perfectly good utility knife right there? Just sayin' .......

    a "prison shank" should be able to be made IN PRISON.

    That means no knives.


    In shop class I make acrylic shanks and sneek them past my teachers all of the time. our shop teacher is so dumb though that he actualy gave someone an A on a shank not knowing what it was

    hmm i bet you could use a dremel to cut a shape and a sanding tip for a dremel to sharpen it.but unfortunatly i dont own a dremel (sucks for me) so i cant try it

    all i have to say is "BOOOOOO!!!!" I'd get bored in iraq and make knifes out of tv screens(they curved ) or chunks of broken tile. you need to try harder or quit.

    You can't get a regular knife past the metal detectors at you-name-it high security area.

    Depending on the "sheet of plastic" used these can be pretty nasty.

    I've seen some made from the lexan/bulletproof/area-51-plastic windows in prisons that were pretty nasty. Slipped right through the metal detectors too.

    But I'll fall in with everyone else and say this is a pretty shoddy demonstration of how to make a plastic knife.

    or u could make a glass or ceramic knife, razor sharp and could probably get past security

    Yeah, depending of the plastic, it can be quite nasty in stabs.... but what if it's got to clash blades like the one in warrior movies with real knives?

    step one you have a knife by step 5 you have a blunt knife a messy bit of plastic and some wasted sand paper

    yeah everyone wants a plastic knife
