Made in the USA, the GyroJaw allows you to clamp angled pieces in straight vise jaws. Placed in the vise between the jaws and the work piece, it pivots on a rounded stud of solid steel while the 2″ by 3-1/4″ face lies flat against the angled stock.
The body of the GyroJaw is made from a combination of nylon and glass fiber, and a slot molded into the face allows you to hold round objects. You can purchase one GyroJaw from the corporate website for $20 shipped, or you can get two for $30 before shipping from Garrett Wade.
