Pieces of sharp rice cutlery for sale (5,3)

I believe the answer is:

price cut

I'm a little stuck... Click here to teach me more about this clue!

'sale' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'pieces of sharp rice cutlery' is the wordplay.
'pieces of' indicates a hidden word (I've seen 'piece' mean this).
'PRICE CUT' is hidden within 'sharp rice cutlery'.

'for' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
