Is it thrust into orange peel? (4)

I believe the answer is:

epee

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

'is it thrust' is the definition.
I can't judge whether this definition defines the answer.

'into orange peel?' is the wordplay.
'into' indicates a hidden word.
'EPEE' can be found hidden inside 'orange peel'.

Can you help me to learn more?

(Other definitions for epee that I've seen before include "Sharp-pointed duelling sword" , "sports equipment" , "Another fencing sword" , "sharp-edged implement" , "Rapier" .)

I've seen this clue in the Evening Standard.
