The SOG knife is definately "sexy" but it's made from relatively cheap stainless. Not going to hold up to abuse the way the Becker knives you are looking at will.
I don't think we have seen any evidence that the laminated stainless blades of Falkniven are any tougher than the much less expensive carbon blades from Becker. However, I would agree that Swamp Rat knives are simply a cut above the rest. ...You have to be willing to wait for them though.
I would recomend the Cold Steel SRK for a 6" blade. It is incredibly tough, you can get one in the $40 - $50 range and is an excellent all-around 'workman like' knife. As has been said before, a 6" blade ain't a 'chopper' but at least the SRK is balanced in front of the handle. If you just have to get the sexy SOG design, CS makes the UWK - it has a black coated Carbon V blade in the same basic shape as the SOG and though a bit lighter, balances in front of the handle like the SRK...
BTW, I really like that new Becker design though (the middle one with the spear point in the above photo)!!! I think I'm going to have to get one of those - while I like the rubber handles on the CS knives a little better than the Beckers, the handles are easily removeable & I figure I'll just wrap it with paracord. Any info on when this knife will be available?
