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, other than the jaws, all parts are stainless steel, brass, or powder-coated for protection. The jaws are coated with black oxide ( gun blueing ). The TRV comes only with the impressive brass palm wheel. Lifetime Guarantee. Made in the USA
