Sharp instruments? (5)
'sharp instruments?' is the definition.
'harps' can be an answer for 'instruments?' (I've seen this in another clue). I'm not certain of the 'sharp' bit.
'sharp instruments?' is the wordplay.
'sharp' can be anagrammed to 'HARPS'.
However, I'm not clear how the anagram is indicated.
Can you help me to learn more?
