You are wise Rasmus San. The poor man must accept guidance from those more knowledgeable than himself.

1. A large Chopper
2. A Medium large blade 7ish inch blade
3. A Medium size blade 5 or 6 inch blade
4. A Small blade 3-4 inch blade
5. A personal always on your body Bushcraft or camp size (4-5 inches)

You Could combine number five with either 3 or 4 and only have blades.

OR you could skip number 2 and then combine number 3 and 4 and and use that for your always on you blade.

Oh and you MUST have a sharpener on you. Personally I like the EZ-Lap model M.
