Tool found in ditch is electronic (6)
I believe the answer is:
chisel
'tool' is the definition.
(chisel is a kind of tool)
'in ditch is electronic' is the wordplay.
'in' indicates a hidden word.
'CHISEL' is hidden in the letters of 'ditch is electronic'.
'found' acts as a link.
(Other definitions for chisel that I've seen before include "Cutting tool used with hammer" , "Carpenter's tool for shaping wood" , "Sharp tool" , "Tool for shaping wood or metal" , "It can be cold in the workshop" .)
