Dad, zealous, carrying hand tool (4)
I believe the answer is:
adze
'hand tool' is the definition.
'adze' can be an answer for 'tool' (adze is a kind of tool). I am unsure of the 'hand' bit.
'dad zealous carrying' is the wordplay.
'carrying' says the answer is hidden in the clue.
'ADZE' can be found hidden inside 'dad zealous'.
Can you help me to learn more?
(Other definitions for adze that I've seen before include "One might cut" , "tool for carpenter" , "Tool used for dressing timber" , "Daze with a kind of axe" , "One used to cut" .)
