The Danvise is truly unique. Body made of Delrin and graphite with hardened steel jaws. Very light weight and great for travel, yet sturdy. Full rotary, too! Includes bobbin cradle and instructional DVD. Excellent Value. The Vise holds hooks of all sizes completely immovable - the jaws are opened and closed using a cam-arm. It can't get any easier - or better. The jaws are made of top quality, perfectly tempered steel. The vise is made in Denmark.
