I just took the Edson steering system on our J/109 apart to service it. A fiddly job that requires undoing a bunch of fasteners in awkward places only accessible through the top of the steering pedestal after removing the compass.
This job was way easier and probably took half as long using my new Wera tools than it would have with my old less feature-rich tools.
The picture above shows just one of the cool features: the sockets are knurled to make it easy to spin off a nut by holding the socket. Particularly useful at that awkward point where a fastening is too loose to activate the ratchet in the handle and too stiff to turn by hand without the added leverage of holding the socket.
