Review on Optimized Spoke Wrench for Mavic Wheel Systems - Park Tool SW-13 by Virgilio Patton

Well-made instrument, typical of Park. This is really helpful, even necessary, in any hope of adjusting or removing Mavic spoke nipples that haven't been touched in years. This gives the leverage and precision fit on the nipple splines needed to rotate the nipples without removing the splines. After that, you really need a basic Mavic spoke nipple tool when trying to fix a wheel or remove a spoke. Because of its length, the tool does not rotate 360 degrees. It has to be constantly removed and reinstalled on the nipple every 1/2 turn because it won't go through the adjacent spoke. It would be better if it was short enough to rotate 360, but then you would lose some of the leverage that a longer tool offers.
