Need to tend a bar on the fly, anywhere in the world? We can’t image why, but whatever. Here’s the ProBostonRoll Delux (no, not a mistake . . . on our part). It’s a roll with clasps and a shoulder strap, and it holds a stirrer, a crusher, a knife, a strainer, a jig, another knife, something called ProFlow (nearly all the tools have silly names like that), a deco waiter’s friend, a lemon zester, a peeler, something called StrainRay (see?), tweezers, a Boston tin with glass, a c-press, a and a juliep. The whole thing will run you $143.
