I could not stand to watch the entire show, I did not want to see any more of Bear's misinformation. The one I watched was the jungle show. He seems to take totally unecessary risks, storms through the bush like a wildman and has no clue how to maintain a knife edge.
As for the knife, it was a knife. Some sort of AF survival knife clone. I did not like the design, that based on using various knives over the decades.
While there is entertainment value to the well informed, we can say "look at that idiot!", I see some serious implications with some people learning really dangerous stuff from the show, if they don't know better.
I believe a half hour of my time is all it will ever get.
