Your fly tying vise has “one damn job” - hold the hook securely. That’s why the Professional is the choice of many pro fly tyers around the world. The vise has four positive locking angle adjustments for stable tying with 360° rotation and is fully machined from high quality stainless steel and aluminum. Combine the stability of the vise with the jaws of a Great White and you have a winner. The jaws have various groove sizes allowing you to clamp down on a wide range of hook sizes securely. Larger to smaller serrated grooves from the back to the front tip of the jaws allows for larger to smaller hooks to be securely locked in.
