Mike,

There is a recent thread on bladeforums:

Now that I'm at home and have access to knife-related sites the blade widths are:

Fixed Griptilian - 0.119"
Fixed Rittergrip - 0.140"
Rand Drop-point - 0.175"
Becker BK7, BK9, BK10 - 0.188"
RAT knives - 0.188"

I lean toward the thinner blades for camp knives. I'm surprised how thick the Rant blade is. I don't think you'd go wrong with the fixed Griptilian.

Reviews for it on REI are good too.
