Small spade (6)
I believe the answer is:
trowel
'small spade' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trowel that I've seen before include "Short-handled gardening tool" , "Small hand tool for scooping" , "Mortar-spreading tool" , "Small hand tool for gardening" , "Gardening implement" .)
