Superb spinner cut (3-5)
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)" .)
