Tool used by feline to get wasp out (7)
I believe the answer is:
catspaw
'tool' is the definition.
(I've seen this before)
'feline to get wasp out' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'to get' means one lot of letters goes inside another.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'wasp' with letters rearranged gives 'spaw'.
'cat' going within 'spaw' is 'CATSPAW'.
'used by' acts as a link.
(Other definitions for catspaw that I've seen before include "Tool" , "stooge" .)
