A picking-up-point (5)
I believe the answer is:
prong
'point' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for prong that I've seen before include "Tooth" , "Spike of fork etc" , "Pointed end of fork" , "Tine of a fork" , "Fork's point" .)
