Such a screwdriver very attractive? Not quite (5)

Ross

I believe the answer is:

sonic

'such a screwdriver' is the definition.
(I know this)

'very attractive? not quite' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'attractive?' becomes 'nice' (nice can mean pleasant or attractive).
'not quite' means to remove the last letter (most but not all of the word).
'nice' with its final letter taken off is 'nic'.
'so'+'nic'='SONIC'

(Other definitions for sonic that I've seen before include "Kind of boom" , "Like mine, possibly" , "of noise" , "Hedgehog" , "Type of boom" .)

I've seen this clue in The Guardian.
