i have been building with knex since i was like 8 or 9 but only recently did i discover the different mechanics you could use in them and more specifically, guns made from them. most of these i got different parts from other people, and then i modified them for my own likings and design standards (all same colors, symmetrical) and i also built a sword and knife, which i believe strongly are the most durable on the internet. if anyone can best them i would love to know because i am a sword fanatic. instructions are to come later, if they are asked for. otherwise most of the pictures are enough.
