Never file and cut recklessly (without thought) (12)

I believe the answer is:

unreflective

I'm a little stuck... Click here to teach me more about this clue!

'without thought' is the definition.
I can't judge whether this definition defines the answer.

'never file and cut recklessly' is the wordplay.
'and' means one lot of letters go next to another.
'recklessly' indicates an anagram.
'never'+'file'='neverfile'
'neverfile' put after 'cut' is 'cutneverfile'.
'cutneverfile' anagrammed gives 'UNREFLECTIVE'.

Can you help me to learn more?
