Allow little margin for error if using wordplay? (3,2,4)

I believe the answer is:

cut it fine

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

'margin for error if using wordplay?' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'allow little' is the wordplay.
'allow' becomes 'cutit' (I can't explain this - if you can you should give a lot more credence to this answer).
'little' becomes 'fine' (similar in meaning).
'cutit'+'fine'='CUT IT FINE'

Can you help me to learn more?

(Other definitions for cut it fine that I've seen before include "Take risks" , "Risk not leaving enough margin for error" , "order to salami slicer?" , "Leave dangerously late" , "Do something with little time to spare" .)
