It's handy for eating at the golf club (5)
I believe the answer is:
spoon
'the golf club' is the definition.
(historical type of golf club)
'it's handy for eating at' is the wordplay.
I cannot quite see how this works, but
'at' could be 'on' (location) and 'on' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spoon that I've seen before include "Wood formerly" , "No knife" , "Eating implement" , "Indulge in sentimental courtship - eating utensil" , "Canoodle" .)
