Weapon produced when atom is split by militant (8)
I believe the answer is:
tomahawk
'weapon' is the definition.
(I know that tomahawk is a type of weapon)
'when atom is split by militant' is the wordplay.
I cannot really understand how this works, but
an anagram of 'atom' is 'toma' which is within the answer.
The remaining letters 'hawk' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'produced' acts as a link.
Can you help me to learn more?
(Other definitions for tomahawk that I've seen before include "Scalping weapon" , "its strike can be fatal" , "Amerindian hatchet" , "American Indian axe" , "Traditional North American fighting axe" .)
