Irish city's sailors producing bottle opener (9)
I believe the answer is:
corkscrew
'bottle opener' is the definition.
(corkscrew is a kind of bottle opener)
'irish city's sailors' is the wordplay.
'irish city's' becomes 'corks'.
'sailors' becomes 'crew' (I've seen this before).
'corks'+'crew'='CORKSCREW'
'producing' is the link.
(Other definitions for corkscrew that I've seen before include "Spiral device for wine lovers" , "Bottle-opener" , "Bordeaux might require this?" , "convoluted course" , "Move in a spiral manner" .)
