My outdoors needs have always been well-met by the big-knife/little-knife strategy. My little knife tends to be the A.G. Russell Deerhunter -- a lightweight scalpel that will handle all small cutting jobs and (*the* most important job) food prep like you won't believe.
For my big knife, I've never really gotten into the large-bowie or kukhri mode. I use a 12" machete, which is reasonably light, has plenty of length, is inexpensive so I'm not afraid to really bang on it, and performs well. It chops small limbs easily and quickly. Here in northern california, it's so easy to find wood, I've not needed a bigger better chopper. If I did, I'd probably go with a bolo or kukrhi.
