Club, truncheon (6)
I believe the answer is:
cudgel
I believe this clue is a double definition.
'club' is the first definition.
(I know that cudgel is a type of club)
'truncheon' is the second definition.
(thesaurus)
(Other definitions for cudgel that I've seen before include "Stout stick used as a weapon" , "Truncheon-like weapon" , "Heavy staff used as a weapon" , "brain" , "Bludgeon" .)
