Creamic bladed knives are great in the kitchen, not so hot in the woods-- too fragile. Definitely NOT for batoning.
For high quality folders, I like Benchmade knives, like the Griptilian, but it is 3.8oz. I've been carrying a 2oz Benchmade Mini Pika lately and I like it a lot. Spyderco makes several similar lightweight folders.
The 111mm Victorinox knives that incorporate a saw are good for emergency shelter pole cutting. Check out the Trekker and Rucksack models--- in the 3.6oz range.
The new Mora Robust model is an excellent and inexpensive fixed blade knife. The Victorinox "Little Vickie" is quite light (3/4oz), razor sharp, excellent for food prep, but not for knocking down small trees.
