Sabre, for example (5)
I believe the answer is:
sword
'sabre for example' is the definition.
(I know that cavalry sword is a type of sword)
This is all the clue.
(Other definitions for sword that I've seen before include "Weapon of steel" , "Weapon, often worn ceremonially" , "Command; social class" , "Weapon with long blade" , "Bladed weapon" .)
