Excellent spinner cut (3,5)

Ross

I believe the answer is:

top-notch

'excellent' 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 "First-rate" , "Excellent (informal)" , "Of the highest quality" , "Wonderful" , "Grade 1" .)

I've seen this clue in The Times.
