I believe the answer is:

cudgel

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

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

I can't explain the remainder of the clue.

(Other definitions for cudgel that I've seen before include "Stout stick; hit with this" , "Batter" , "brain" , "Stout stick used as a weapon" , "Stick-like weapon" .)

I've seen this clue in The Irish Times and the Irish Times (Crosaire).
