Shimano M700 AKA / Overbury's Crossfell / Deerhead headset tool ........do I need one?? can I improvise?

[Darcus]

So I've just acquired this original Overbuys Crossfell with the said headset on it, and would like to service it.....question is though how to I undo it with what looks like a special tool? Anyone done this before? Any tips gladly received! Thanks

Pair of slip joint pliers, wrap the ends with some electrical tape to stop scuffing and grip gently.....

There is a chap in Poland (IIRC) making some reproduction spanners for these at not too much money. They are better known as a 600 EX headset spanner I think.
