Crossword Genius

Cut material, fixed amount (10)

Ross

I believe the answer is:

laceration

'cut' is the definition.
(I've seen this before)

'material fixed amount' is the wordplay.
'material' becomes 'lace' (lace is a kind of material).
'fixed amount' becomes 'ration'.
'lace'+'ration'='LACERATION'

(Other definitions for laceration that I've seen before include "rent" , "Tearing (of skin)" , "Cut, scratch" , "cutting" , "wound" .)

I've seen this clue in The Telegraph.
