I've actually tested out PickPocket upon its release back in BW1. With Sash, it doesn't take the item after Sash's activation; which leaves something to be desired. Thief and KnockOff are actually better moves to use over the ability itself. A Gem could work, however, but it'd need to be used when Weavile is sure to survive the attack.
