A handy skill? (7)
I believe the answer is:
sleight
'a handy skill?' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sleight that I've seen before include "Conjuror uses this" , "Artful trick" , "Dexterity (usually of hand)" , "distraction?" , "Skilful deception" .)
