Cut charge on shoestring (8)
I believe the answer is:
lacerate
'cut' is the definition.
(I've seen this before)
'charge on shoestring' is the wordplay.
'charge' becomes 'rate' (rate is a kind of charge).
'on' means one lot of letters go next to another.
'shoestring' becomes 'lace' (I've seen this in another clue).
'rate' put after 'lace' is 'LACERATE'.
(Other definitions for lacerate that I've seen before include "Tear, wound, hurt" , "Tear roughly, cut jaggedly" , "Harrow" , "Clear tea (anag.)" , "Tear or make deep cuts" .)
