Flat-bladed gardening tool (3)
I believe the answer is:
hoe
'flat-bladed gardening tool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hoe that I've seen before include "Tool; promontory" , "Tool for loosening soil and scraping up weeds" , "Weeding tool" , "Gardening tool" , "Plymouth - -" .)
