If you have aluminum cylinder head, be careful about unscrewing the spark plugs while the engine is too warm.

That tool is a Hazet 2771 Valve Adj. Wrench (MB Part No. 110-589-01-01-00). It is essentially a 17mm open end wrench with a slight offset on the handle. The wrench engages the last ridge on the boot and with a prying action pulls it straight off. It works great on the M112 where there is little clearance for a pair of 'boot pliers'. Not sure if it's applicable to other engines.
