Boasts about pub using levers (8)

I believe the answer is:

crowbars

'levers' is the definition.
(crowbar is a kind of lever)

'boasts about pub' is the wordplay.
'boasts' becomes 'crows' (crow is a kind of boast).
'about' means one lot of letters goes inside another.
'pub' becomes 'bar' (I've seen this before).
'crows' going around 'bar' is 'CROWBARS'.

'using' is the link.

(Another definition for crowbars that I've seen is " Iron rods used as levers".)

I've seen this clue in The Telegraph.
