You are right. That is why I bought some items that were reviewed and recommended on Dougīs site (thanks for the good advice). For play-it-save equipment this site is excellent.
I saw some episodes with Les Stroud and found some useful information but you notice that he avoids to take too much risk. So his tools may be worth considering if you need a new tool.
However with the BG knife it is different for some people. They buy the spirit of adventure and get a free knife with it. That is an advantage in marketing as it offers access to more customers.
