The Hook Jaw is a new 2023/24 design made from standard jaws with a moon shape cut out. The hook jaw will give you extra access to make small flies, Euro jigs/ and are ideal for small Gamechangers. Head only fits Medallion style vises. Hook sizes are similar to the Stainless Steel style.
Jaws can be ordered as a head for Revolution or can be set up as a vise with any base or clamp. Contact me for more info.
