I'm obliged to exercise caution, handling large knives etc (9)
I believe the answer is:
tableware
'knives etc' is the definition.
I can't judge whether this defines the answer.
'i'm obliged to exercise caution handling large' is the wordplay.
'i'm obliged' becomes 'ta' (I can't justify this - if you can you should give a lot more credence to this answer).
'to exercise caution' becomes 'beware' (I've seen this in another clue).
'handling' is an insertion indicator.
'large' becomes 'L' (eg in clothes sizes).
'beware' placed around 'l' is 'bleware'.
'ta'+'bleware'='TABLEWARE'
Can you help me to learn more?
(Other definitions for tableware that I've seen before include "knives, etc" , "Crockery, cutlery, etc." , "Bowls, for example" , "Dinner service" .)
