Bobbin ThreaderMeet the new addition to the growing Spinoza fly tying bench! We've fielded a few requests for these over the years, and made these up over the winter. Machined from brass bar stock with a knurled base, we've also stamped these guys with our "Spinoza" cartouche. The threading wire is soldered into the base making these a simple, fun little tool and a perfect match for your Spinoza dubbing needle!
