Journalist spotted cutting implement (7)
I believe the answer is:
hacksaw
'cutting implement' is the definition.
'hacksaw' can be an answer for 'implement' (hacksaw is a kind of implement). I'm not certain of the 'cutting' bit.
'journalist spotted' is the wordplay.
'journalist' becomes 'hack' (hack can informally mean a journalist).
'spotted' becomes 'saw' (spot can mean to see).
'hack'+'saw'='HACKSAW'
Can you help me to learn more?
(Other definitions for hacksaw that I've seen before include "7 for metal" , "Toothed tool for cutting metal" , "One cuts" , "means of cutting lead article?" , "Metal cutter" .)
