I dont know much about bear grylles or whoever he is but someone gave me three of those knives with his name on them about a year ago. The review is.... they sucked....worst piece of steel marketed as U.S. steel. The handles I would give an eighty out of one hundred grade.thin light and strong. Sometimes kinda pinches your hand with the small one. Nice grip and I loved the orange. Easy to see when you lay it down. The blades the worst tempering job ever on a knife remotely close to this price range.( mine were free) the edges rolled if you tried to flatten the angle more than a cold chisel. They were so bad I had swore off gerber forever. I thought they had moved their manufacturing to china or something. Maybe I ll give them another chance.......sorry Colt
