Worry about Victor's cut (5)
I believe the answer is:
carve
'cut' is the definition.
(I know that carve is a more specific form of the action cut)
'worry about victor's' is the wordplay.
'worry' becomes 'care' (eg without a care means without a worry).
'about' is an insertion indicator.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'care' going around 'v' is 'CARVE'.
(Other definitions for carve that I've seen before include "Cut (cooked meat)" , "Attack the turkey" , "Truncheon" , "Cut meat with sharp knife" , "fashion" .)
