Although these days I EDC a folder and a Victorinox Tinker, in the past I've had very good luck with the Classic. There is still a Classic attached to my EDC backpack.
I've twice hiked the entire length of the 2,650-mile Pacific Crest Trail from Mexico to Canada through CA, OR and WA. Both times, I carried ONLY the Classic, and it was entirely adequate for the variety of cutting tasks I encountered: cutting cardboard resupply boxes; repairing/modding gear; opening food, slicing bagels and cheese, cutting fruit, removing splinters, cactus spines, and ticks; picking teeth; trimming/filing finger- and toenails; minor surgery; shaving delicate little fuzz sticks for firestarting; etc. I cleaned trout with it only a few times, and if I was doing this often a different blade would be better.
Long-distance hiking is a sorta specialized pursuit, and a different activity than "camping", but still, it is remote and one encounters a huge variety of situations, seasons, environments. A widely-read writer on long-distance hiking highly recommends the Classic, and I think that is part of why it is so popular among long-distance ultralight hikers.
In one week, my wife and I are leaving to hike the 2,800-mile Continental Divide Trail. She's carrying the Classic, and I'm carrying a 7.5" custom fixed-blade knife, because I'm a knife knut these days! But, if for some reason we could only have one knife, of course I'd just bring the Classic. If I get tired of the weight this summer, I'll ship my FB home and pick up a Classic at any small-town hardware store along the CDT.
Highly recommended. A huge amount of utility for 0.9oz and $2-$3 shipped on eBay. Also, the most useful knife is the one you have with you when you need it. No worries about "pocket bulge" or losing a $3 knife.
EDIT: Sure, most of the other knives we talk about here are better for stabbing terrorists and de-animating ninjas, but as you can tell I am a big fan of the EDC utility of the Classic. I've really enjoyed reading the posts by other knuts who have found it very useful for everyday cutting too.
