Turns out Bear doesn't actually do any survival - instead he's 50 feet from a high way and stays in a cushy hotel at night. Maybe its the TV show and producers don't want him hurt, but then again its called false advertising.
I do have one of his hunting knives, and its just a cheap piece of crap just like his show is really, most of the knife is serrated which makes it useless for woodlands, although I only paid $15 for it, I thought it was a serious knock off of the military knife KMF II Infantry black.
I used to carry the knife with me all day long, but lately I switched to the Gerber knife, seems to much better handling with a better rubber grip.
Bear's knife went dull after the first 6 months, Gerber hasn't dulled yet, still sharp as day I bought it.
