The Super II Vise incorporates a specifically designed jaw that is ideal for small hooks, and also serves well for general duty on hooks up to size 2. The jaw allows access to the rear of the hook, where wrapping and tying on fly materials can be a problem when using a conventional vise. Jaws can be rotated or fixed at any angle without releasing the hook. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Vises.
