Each is elated about implement (6)
I believe the answer is:
chisel
'implement' is the definition.
(chisel is a kind of implement)
'each is elated about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'CHISEL' can be found hidden inside 'each is elated'.
(Other definitions for chisel that I've seen before include "Tool for shaping wood or metal" , "Hammered cutting tool" , "Tool with bevelled edge for shaping wood" , "Flat steel tool with a cutting edge" , "Sharp-edged metal tool" .)
