Product of plant making unconventional weapons (4,3)
I believe the answer is:
snow pea
'product of plant' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe there's a link between them I don't understand?
'unconventional weapons' is the wordplay.
'unconventional' is an anagram indicator.
'weapons' is an anagram of 'SNOW PEA'.
'making' is the link.
Can you help me to learn more?
(Other definitions for snow pea that I've seen before include "pulse" , "Mangetout (US)" , "American plant" .)
