TheRotary Vise offers important features to tyers who primary focus on tying trout flies. The vise arm holding the jaws is articulated allowing up and down movement in addition to its 360-degree rotation. This is extremely helpful when tying small flies because the fly can be positioned in the most comfortable position for the tyer – allowing plenty of finger clearance while tying. The two-part jaws are fully adjustable allowing the vise to accept hooks of nearly every size. The vise also comes supplied with a handy bobbin cradle and extra-large c-clamp.
