I have a bunch of them, always had great service with them.
Carried a Mini Reflex for a decade in uniform. It is retired now, deservedly.
Since someone asked about the lightweights with the plastic scales, I have been carrying/using a Casbah daily for about three years now. It has held up just fine, digging under my fingernails, cutting boxes, wire, skinning numerous critters, and it always serves well when someone brings a cake to work.
It is kind of a pain to clean icing/fat/blood/guts, etc. out of it, but I'm still carrying it, so it's ok.
It IS noticably lighter than it's Griptilian brother that is almost exactly the same size.
