The Peak Rotary Vise is designed for optimal tying efficiency and ease of adjustment. Materials (including Stainless Steel, Brass, Tool Steel, and Aircraft Aluminum) are chosen to last a lifetime. Hardened and tempered tool steel jaws hold hooks securely, from size 2/0 (depending on exact hook wire diameter) down to the smallest on the market. The large stable pedestal base will hold this vise where you set it and the non-marking feet will protect the surface you set it on. The steel base is powder coated white for a durable surface that provides a backdrop you can see your materials against. The base also includes an integrated hook/bead pocket with rounded edges for ease of removal and two accessory post mounting holes (accessory post not included).
