One of the first pasta tools I acquired was a pasta wheel (aka a pastry wheel). I now own a small collection of this essential tool. I use my favorite one all the time when sheeting pasta, cutting shapes (pappardelle and trenette) and when making stuffed pasta. I bought this dual wheel cutter at Antica Aguzzeria del Cavallo (here) during a pasta pilgrimage to Bologna. You can now buy these sturdy tools outside of Italy. Emiliomiti (here) sells a straight wheel, fluted wheel, dual cutter and even an adjustable quad cutter. These heavy-duty brass cutters will last a lifetime.
