One making tears in jumper, épée waving around (6)
I believe the answer is:
weeper
'one making tears' is the definition.
'in jumper epee waving around' is the wordplay.
'in' indicates the answer is hidden within the clue.
'around' is a reversal indicator.
'repeew' is hidden in the letters of 'jumper epee waving'.
'repeew' written backwards gives 'WEEPER'.
(Other definitions for weeper that I've seen before include "down, evidently?" , "One who cries" , "One greeting" , "upset one" .)
