Superb spinner cut (3-5)

Ross

I believe the answer is:

top-notch

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

'spinner cut' is the subsidiary indication.
'spinner' becomes 'top' (something that spins).
'cut' becomes 'notch' (notch is a kind of cut).
'top'+'notch'='topnotch'

(Other definitions for top-notch that I've seen before include "Grade 1" , "First-rate" , "Wonderful" , "Superb" , "Excellent (informal)" .)

I've seen this clue in The Telegraph.
