Larger kitchen implement, did you say? (7)
I believe the answer is:
greater
'larger' is the definition.
('great' can be similar in meaning to 'large')
'kitchen implement did you say?' is the wordplay.
'kitchen implement' becomes 'grater' (I've seen this before).
'did you say?' indicates a 'sounds like' (homophone) clue.
'grater' sounds like 'GREATER'.
(Other definitions for greater that I've seen before include "Bigger, larger" , "More renowned" , "of more importance" , "More extensive" , "more influential" .)
