Like darts that hurt, piercing Cockney bloke (6)

I believe the answer is:

arrowy

'like darts' is the definition.

'that hurt piercing cockney bloke' is the wordplay.
'that hurt' becomes 'ow' (I've seen this in other clues).
'piercing' is an insertion indicator (some letters pierce a hole in others).
'cockney bloke' becomes 'arry' ('Harry' - common masculine name - said with the 'H' dropped - a cockney accent.).
'ow' placed inside 'arry' is 'ARROWY'.

I've seen this clue in The Times.
