Knife Edge clamps are designed for maximum holding strength on rough or cast surfaces. Their hardened serrated jaw "bites" into the material, making them ideal for clamping irregular stock there traditional smooth clamps might slip. These low-profile clamps pull the part down and in, ensuring both vertical and lateral stability. They're commonly used in roughing steups or first-op fixtures.
