Piece of cutlery (8)
I believe the answer is:
teaspoon
'piece of cutlery' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for teaspoon that I've seen before include "Cutlery accompanying a cuppa" , "Small medicine dispensing unit" , "Cooking unit" , "With OAP onset, use it at table" , "Not Aesop (anag.)" .)
