How much are you willing to pay? In a folder, you really aren't going to get something for use as a crowbar (why bother when you can get a small prybar for less then $20). As for chopping/batonning wood. I always suggest people don't get a knife with too goofy of a blade shape. The shapes that have been around for a long time have been around for a reason, they work. Knives I personally have used and would recommend are the Gerber EZ-out in a plain edge. Very light, good edge. The handle is thin but comfortable. Also the Spyderco Native III, also in plain edge (I don't particularly like serrated blades). Slightly heavier then the EZ-out, but not by much. Both have good lock back, locking blades. I also recently picked up and Opinel #7. Very simple knife. The blade is thinner then a lot of other knives, but takes a very good edge. The knife also has a simple, non-automatic locking ring.

The Opinel was about $10, the Gerber EZ-out ~$20 and the Spyderco Native ~$40.

Also if you know you're going to be doing a lot of chopping, a light ax, hatchet or tomahawk will serve you better then a heavy knife. I find the combination of a smaller lighter knife with a tomahawk works very well. The knife's blade stays sharper and is more effective and controllable then a larger knife used for both tasks. And the tomahawk can be used to chop or the head can be used as a wedge for batonning. Plus I find hatchet or tomahawk more comfortable to carry then a large knife since all the weight is concentrated in the head, which is right at your belt and doesn't flop around.
