I believe the answer is:

epee

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

'item for fencing' is the definition.
I can't tell whether this definition defines the answer.

'sweeper holds back' is the wordplay.
'holds' says the answer is hidden in the clue.
'back' is a reversal indicator.
'eepe' is hidden within 'sweeper'.
'eepe' back-to-front is 'EPEE'.

Can you help me to learn more?

(Other definitions for epee that I've seen before include "Olympic event" , "Rapier" , "Pointed weapon" , "Duelling blade" , "Fencing blade" .)

I've seen this clue in The Hindu.
