The Shuffler’s companion tool (available separately as is the box) is our nickel plated brass pin vise. With 2 ground, exchangeable tips, this tool picks up nipples from the Shuffler to thread onto spokes during lacing. It is actually a 4 sized (2 collets) wrench but we only use one size for the included 13g tips. Also a big success, we sell quite a few by themselves for those with alternatives to the Shuffler.
Users (thanks Ryans!) suggested the pin vise would be more handy if it would stand up during a pause in lacing. The result is an added bearing that turns easily in your palm (as the previous wood handle) and looks great.
And now you can park the tool anytime during lacing, with or without a nipple on its tip.
