Very mixed advice here. Plenty of it good, but the rest makes it confusing.
Knives are tools. What you plan to do with one will determine what the best tool for the job is. It would help if you assign specific tasks for your knife before you decide. Don't give the lazy 'everything' answer. The climate and wilderness around you pose specific challenges.
Instead of looking for a do it all knife, add a small hatchet to your kit. The Fiskars X7 hatchet only weighs 1.5 pounds. If you place one in your pack, your capabilities are far greater than any knife will give you. With that in your kit, a ~4" drop point blade is all you need. I would get the Fallkniven F1 myself, but many of the choices mentioned here are equally good. That knife should be on your hip, so pick a comfortable and secure sheath.
If you don't like the idea of a hatchet, then a larger knife would be better. Maybe a Fallkniven S1, or Esee 6, or again, many of the good larger knives recommended here. Whatever you get, be sure a great sheath is a part of the package, even if you have to buy one.
For either scenario, you also need a backup knife. A Mora stainless Companion adds a mere 4 ounces to your pack, which includes the usable plastic sheath. This will also give you a clean, sharp knife for food processing.
Don't forget a Bic lighter. You can use it to start your fire when the babes are not around
