Boss reported Irish county club (10)

I believe the answer is:

knobkerrie

I'm a little stuck... Click here to teach me more about this clue!

'club' is the definition.
(knobkerrie is a kind of club)

'boss reported irish county' is the wordplay.
'boss' becomes 'knob' (I've seen this before).
'reported irish county' becomes 'kerrie' (I can't justify this - if you can you should give a lot more credence to this answer).
'knob'+'kerrie'='KNOBKERRIE'

Can you help me to learn more?

(Other definitions for knobkerrie that I've seen before include "club" , "Stick" , "South African wooden weapon" .)

I've seen this clue in The Times.
