Well, the responses here started with sarcasm, ended up with some real good info - quite an education. Amazingly, that $700+ knife will throw sparks like a flint and a worn-out hacksaw blade chunk will. Also, serving yourself some termites with one seemed efficient, too. I'll use my Buck 110 to open a pack of wooden matches - and, later, a pack of hot dogs. You betcha I have camped... but, roughing it now, for me, is best effected by a stay in Motel 6.
Hats off to Mr. Grylls, he has proven his metal - and does provide good entertainment. He can have all of the help he needs - and sleep where he wants. One must remember, commercial TV exists to sell advertising... it is entertainment - even the news, recalling their "If it bleeds, it leads!" axiom. Thanks to all for the great 'entertainment' and education I got re Bear Grylls and his knife, a neato example, even if I can't afford it. Yeah, even the early sarcasm was 'entertaining'!
