More important kitchen utensil would you say? (7)
I believe the answer is:
greater
'more important' is the definition.
('great' can be similar in meaning to 'important')
'kitchen utensil would you say?' is the wordplay.
'kitchen utensil' becomes 'grater' (eg a cheese grater).
'would you say?' indicates a 'sounds like' (homophone) clue.
'grater' is a homophone of 'GREATER'.
(Other definitions for greater that I've seen before include "more influential" , "Bigger, larger" , "more imposing scale" , "More significant" , "More renowned" .)
