I heard a lot people omit the "in" while saying "in a right way".
for example
if a kid play with a knife, someone would told him/her "you are not using the knife a right way"
is it grammatical and idiomatic?

This question was already answered in the comments, however for the sake of completeness -
Both your sentences are grammatically correct when a is replaced by the.
You are not using the knife the correct way
You are not using the knife in the correct way
