HMH’s latest and greatest addition to their vise line. The TRV is the first vise HMH has made with a True inline Rotary action. This means the hook shank can be aligned with the axis of rotation of the vise, allowing materials to be held while the hook is rotated. Great for dubbing loops, chenille, tinsel, or palmering a hackle! Jaws are cast in true HMH style out of tool steel, and other than the jaws, all parts are stainless steel, brass or powdercoated for protection. The Jaws are now with black oxide (gun blueing) coating. The TRV comes only with the impressive brass palm wheel but for those who must have a rotation arm, one is now available.
