Grasping tool had tortured prince (6)
I believe the answer is:
pincer
'grasping tool' is the definition.
'pincer' can be an answer for 'tool' (pincer is a kind of tool). I'm not sure about the 'grasping' bit.
'tortured prince' is the wordplay.
'tortured' indicates anagramming the letters (I've seen this in other clues).
'prince' anagrammed gives 'PINCER'.
'had' acts as a link.
Can you help me to learn more?
(Other definitions for pincer that I've seen before include "Surrounding (movement)" , "Crab's claw" , "Crab's nipper" , "Front claw" , "Grasping limb of a crustacean" .)
