Hoping to get something sharp (3)
I believe the answer is:
pin
'something sharp' is the definition.
'hoping to get' is the wordplay.
'to get' indicates a hidden word (I've seen 'gets' mean this).
'PIN' is hidden in the letters of 'hoping'.
(Other definitions for pin that I've seen before include "Fasten; a security code" , "Secure" , "form of identification" , "Debit-card number" , "Fixing device" .)
