Invention on Instagram: "The process shown is the machining of fresh serrations into an aluminum vise jaw. A smooth jaw blank is clamped into a machine and a cutting tool forms evenly spaced teeth across its surface. These teeth are what allow the vise to grip a workpiece securely instead of relying only on clamping force. Aluminum jaws are often used to protect softer or finished parts from damage while still providing reliable holding power. Cutting precise serrations increases friction and pr
