Apart from this one that they sell.http://www.wiggle.co.uk/topeak-hexus-ii ... ulti-tool/
I've been using a Park Tool CT-5 for ages, on 10- and 11-speed chains, without any difficulty. Magic Links are preferable (more because they make it easy to remove the chain for cleaning) but the CT-5 has happily inserted a number of Shimano 11-speed joining pins.
No need for a special tool to open the split link. Just move the chain to the big ring with the split link half way around. Shift the chain links on the right side of the link to the left by one link, such that the chain bunches at the link. Give it a tap with the back of your multi tool and the link will magically open. After all, your not going to carry the special pliers in your saddle bag.
