Gripping part of hobby (5)
I believe the answer is:
talon
'part of hobby' 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 talon that I've seen before include "ogee moulding" , "part to make savage cuts" , "Raptor's claw" , "Large claw" , "Bird's claw" .)
