Exonautic"FRN (Fiberglass Reinforced Nylon) and GFN (Glass Filled Nylon) are the same thing, a nylon-based plastic that is reinforced with Glass Fiber and injection molded for use in knife handles (among other things). FRN and GFN handles are one of the cheapest and toughest handle materials to produce in large scale production knives.
Even though Glass Filled Nylon is perceived as a cheaper material, which it is, it makes for a very tough knife handle material and can take some serial abuse. It is quite a bit more flexible than G-10 and other Resin Laminates, so does not have the rigidity associated with them, however it makes up for this in it's impact toughness. Additionally, nearly any texture can be created on the surface of an FRN handle because it is injection molded, making it a very versatile material to work with with infinite possibilities."
jason.rthank you, i was reading about alot of the manufacturing side of things, like ratios and compositions but you gave me what i needed on performance wise.
