My own experience with Spyderco knives say that if i need a lightweight tool, at same time a durable enough handle I use a Spyderco with a FRN handle.
In my daily routine(running, walking with dog, job....) when I carry Spyderco Delica FRN I don't feel that I have knife. FRN is so lightweight when that you see it.
I have knives eg. with G-10 or titanium , but I don't see really advantage over FRN.
FRN is very good material for knife handles. FRN is "lightwieght and extremly strong, .....".
It' s true . FRN rulez!
