The S6 is an absolute classic.. It is a lot more versatile than the DF imho (chopping v. battoning!), plus as it's lighter and smaller it's more likely to be carried thus there when needed... Best field knife going right now.
I agree 100%, perfect size. A machete is handy, but I would not carry one hiking. Under 7" greatly increases the odds of having it with me when I need it.
