One who might be best to hide revolutionary weapon (7)
I believe the answer is:
machete
'weapon' is the definition.
(I know that machete is a type of knife)
'one who might be best to hide revolutionary' is the wordplay.
I cannot really understand how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
'revolutionary' could be 'che' (Che Guevara the Marxist revolutionary) and 'che' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for machete that I've seen before include "Broad heavy knife common in Central America" , "Heavy South American knife" , "cutter" , "The mace (anag.)" , "hacker" .)
