Clipper
Good all-round bushcraft knifes are the clipper 840 or 860:
The 860 (blue) is stainless so perhaps better for general purposes. 840 (red) is carbon steel so it works good with a firesteel and is perhap a little easier to make really sharp. But will rust if you don't take good care of it. The 860MG is a stainless clipper with green colouring. But I like the blue, easier to find if you drop it. There is also an orange 860 Rescue variant.
Classic
For the purist bushcrafter who wants to flirt with the vintage look, the Classic Mora No 2 (or one of the other Classics) is a very good choice:
Also carbon steel. Very good for crafts and carving. Small and really nice. There are bigger classics as well.
Mora 2000
A little more advanced is the Mora 2000:
A strong and powerful knife. Nice, but hasn't got that special simple "Mora" feel. But is a very good knife. A little expensive compared to the others.
Viking
If you want some spare knifes, perhaps to lend out or give away, then the Viking series is really cheap, but has just as good a blade as the clipper. The 640 (red) is carbon steel, the 660 (blue) stainless.
Perfect for people who use a knife at work. Not easy to loose either. And if you do, it's cheap!!!
Scout
A good first knife for kids is the Scout No 39. Good for small hands and has a good guard:
But the slightly bigger Scout No 40 is a good safe knife for adults as well.
-----------
Start with a stainless Clipper 860. Add a Mora Classic No 2 for advanced bushcraft.
