I would buy one from Unbrako or similar, multi tools tend to be fairly soft.
Also Bondhus, Wera, probably others but these are the brands I know to be good.
Park Tool did the job - they reckon they are high quality, workshop grade, and the grub screw had no threadlock on it, so it span straight out. Happy days.
On to the damper...yay.
