When the knife becomes big enough one may need a small knife beside it for small work
and the weight and bulk may compare to a small axe (hatchet/tomahawk/whatewer) which for many tasks often performs better than a big knife.
Then it comes down to personal needs and preferances.
Myself I have far too often been out there with a small and big knife,
and an axe

. And then the big knife is not used a lot.
Fortunately I got some light but very practical and useful 8 and 9"
Same knives for when I
insist on carry a big knife

.
I can therefore leave the big
and heavy knives at home when the urge comes.
As long as bear defence is not an issue a small folding saw usually outperforms any big knife or an axe anyway for camping use
