Everyone has their own opinion on this one!
It is very much a personal issue, what I call the perfect bushcraft knife will be very different to someone elses view.
A good way to go is to get a long to a meet-up, everyone brings different pointy things along and they are a good chance to try out some of the designs available.
A good choice until you have found the perfect blade, is one that I use most often and recommend to anyone new to the craft - an Opinel No7 (attached with cord to your belt loops and kept in your pocket along with a firesteel, a keyring light and a whistle) and in my daysack a traditional scandi (a Mora, or Issakia, or my Lauri PT).
The Opinel takes care of about 80% of my cutting needs (food prep, cutting cordage, harvesting plants, etc), the scandi get used for carving, splitting and making feather sticks.
Very few knives will excel at all tasks, what is great for carving wood is rarely good for peeling veg or spreading jam!
Give it a try until you find the perfect knife (for me the F1 comes closest, but every once in a while, something new and shiny shows up and a waver for a while) and then I fall back on the No7 and my Lauri!
