"I see one knife, not two."

Translation: Vidím jeden nůž, ne dva.

[PierreMDL]

"Jeden nůž vidím, ne dva.", why wouldn't it be correct?

[VladaFu]

You are contrasting the objects, jeden nůž vs. dva (nože). Hence they should both be final in their respective clause.

You could say: Jeden nůž vidím, ale dva nevidím. I see one knife but I don't see two. This contrasts the verbs so the verbs are final. They can also be both first.

I wrote vidím jeden nůž ne dva nože. I believe this should be the correct sentence. Other way the sentence is becoming grammatically wrong, isn't it?

[VladaFu]

no, it is not

Thanks!

Shouldn't "nuz" be in accusative?

[VladaFu]

It is, masculine inanimate words (hrad, stroj) have the same forms for nominative and accusative.
