    KNEX KNIFE- Noun 1. A non dangerous, fun knife to play with.

    KNEX is a toy for 8 year olds

    Objection! KNEX can be used by ANYONE. They may not be as popular as LEGOS, but anyone can use them.

    ya knex is a toy for 8 year olds when your makin little 2 piece crap but not when your makin freakin bazookas and snipeer rifles

    yeah, but the point is, it's not going to be really sharp or made of metal.

    yea a knex knife is a little childish but a sniper that shoots sharpend shots or a bazooka that shoots large projectiles extreamly fast isnt really for an 8 year old

    yeah. Most of the guns on here EXPLOIT the knex principle. Most of the Knives on here stay within the knex principle...

    every single knif instructable i see you post the definition for knife will you pleas stop ex: KNIFE –noun 1. an instrument for cutting, consisting essentially of a thin, sharp-edged, metal blade fitted with a handle. that was first and only said by stevolution
