Renzetti Ambassador Blane Chocklett is the most innovative Fly Tyer in recent years. His persistence and many years of developing a fly with the movement of conventional lures let him to the most recent boom in fly tying. Truly a gamechanger. His style of fly can be applied to any species and hook size. While our current vise jaws allowed Blane and many other fly tyers tie thousand of articulated flies for years, It truly was the most practical design for it. Blane and Andy Renzetti worked together in designing a jaw for the fly tyers to use when tying articulated flies. As Blane mentioned, the Game changer Jaw makes the whole tying experience easier and faster. We currently are offering these jaw to fit the Traveler and Presentation Series. Working on a shank jaw for the Master and Saltwater Series. Made in the USA
