Umpqua's Standard Ergo Bobbin feature a stainless steel frame with a unique slightly-twisted arm design that allow thread spools to be cradled closer against the fly tier's palm for increased comfort and control. With a smooth ground, finely polished ceramic tube that helps reduce frays and premature grooving, Umpqua's Standard Ergo Bobbin comes trimmed with a handsome brass grip and polished ball-ends for flawless spool rotation.
