I actually prefer something larger for hiking- because for me, hiking means I'm not carrying much and I may end up in a survival type situation (needing to make shelter, etc).
But, if I'm camping- meaning I brought a tent, etc. and I can only have one, my Bark River NorthStar (or maybe a Fox River when I get one). I'm kind of shocked I'm the first to mention a Barkie. I think this is a great size for food prep and the kind of stuff you run into around camp.
Usually, I would like something a little bigger and a little smaller- say a Camp Tramp (excellent score on that!) and a Dozier Gentleman's knife or possibly my Active Duty now that I finally got one.
