Razor user lopped recycled pork cut (6)
I believe the answer is:
ockham
'razor user' is the definition.
The definition suggests a singular noun which matches the answer.
'lopped recycled pork cut' is the wordplay.
I cannot quite see how this works, but
'cut' could be 'ham' (ham is a kind of cut) and 'ham' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for ockham that I've seen is " William of --, English philosopher".)
