Park precision spoke nipple wrench. This is the genuine professional version of the spoke wrench that everyone else copies.

This is the SW-2 model, which is for nipples sized 0.136" (which is 3.45mm) which is typically the correct size for Japanese and many Taiwanese nipples. As always, measure first - or buy one of each size so you always have the right size on hand.
