Cutting-edge journalist got spotted (7)

Ross

I believe the answer is:

hacksaw

I'm a little stuck... Click here to teach me more about this clue!

'cutting-edge' is the definition.
I can't tell whether this definition defines the answer.

'journalist got spotted' is the wordplay.
'journalist' becomes 'hack' (I've seen this before).
'got' says to put letters next to each other.
'spotted' becomes 'saw' (I've seen this in another clue).
'hack'+'saw'='HACKSAW'

Can you help me to learn more?

(Other definitions for hacksaw that I've seen before include "Blade in a frame under tension" , "something to cut copper?" , "Metal cutter" , "means of cutting lead article?" , "something cutting" .)

I've seen this clue in The Mirror.
