A handy and wildly popular device, the HMH Premium Tube Fly Tool lets you tie tube flies on any standard jaw vise, not just HMH's. Simply clamp the tool into place, attach a plastic or metal fly tube via the mandrel, affix and begin tying! Kit includes the Tool Body, two tapered, stainless steel mandrels (.041" & .062"dia) designed fit any style HMH tubes, four cut-to-length plastic fly tube samples, flexible junction tubing; and of course, detailed user instructions.
