buying a field/hunting /tactical knife

G'day to all since I first became a member on E-bay I've been shocked by the large number of no name knives claiming to be top quality. So I'd thought I'd write a guide based on my experience over the years, I've been making knives for 17 years now I'ts a hobby for me and often I've steered people to a knife that suits the task that it is required for eg: a person I know bought a Rambo style "survival knife " for hiking and camping he used it for chopping wood and no surprise it broke he bought the knife to me asking if I could fix it I advised him to thow it in the bin and buy a decent knife, he ended up getting a Becker companion knife.The Blade: Firstly look at the steel I prefer aus 8 used by sog {my preferance in blades} but the tops steels in my view aus 6, aus 8, ats 34 ,bg 42,D2 and some 440 stainless
