Some secateurs can scratch! (3)
I believe the answer is:
cat
'can scratch' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'some secateurs' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'CAT' can be found hidden inside 'secateurs'.
Can you help me to learn more?
(Other definitions for cat that I've seen before include "Feline mammel" , "See 21" , "Feline - whip" , "Feline mammal" , "Tabby" .)
