I believe the answer is:

subtracted

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

'took away' is the definition.
(to subtract is to take away)

'bad cutters for re-setting' is the wordplay.
'bad cutters' anagrams to 'SUBTRACTED'.
However, I'm not clear how this is indicated.

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
