From the pine, it's not a needle (3)
I believe the answer is:
pin
'needle' is the definition.
(both can mean a sharp point)
'from the pine it's not a' is the wordplay.
I cannot quite see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
A single letter 'p' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pin that I've seen before include "Flagged stick placed in golf hole" , "Small object to fasten or attach" , "Fixing device" , "Secure" , "Small pointed metal fastener" .)
