I find myself carrying FRN knives more than others because of its qualities: light, durable, thin knives, good grip, etc.
As far as fading (from use, from the sun), G10 and natural materials will also so and perhaps at a higher rate. Its not really a problem and certainly not unique to FRN.
People hate on it because it is a plastic and many fail to realize that its an advanced polymer, not merely tupperware material. Like I always say, it works on my Glocks, it works on my knives as a handle. Bottom line is, it works great for US, from first hand experience. Who cares what they think. Let them carry their heavy thick Edc's in the middle of summer while carrying a Glock and everything else LOL.
