Knitter modified knick-knack (7)

I believe the answer is:

trinket

'knick-knack' is the definition.
(I've seen this before)

'knitter modified' is the wordplay.
'modified' indicates an anagram.
'knitter' with letters rearranged gives 'TRINKET'.

(Other definitions for trinket that I've seen before include "Small piece of jewellery of little value" , "Cheap ornament" , "Inexpensive ornament" , "Bauble, geegaw" , "Gewgaw" .)

I've seen this clue in The Guardian.
