What are punch knives
Punch knives function as specialized cutting tools that pierce or shape materials through vertical force – operating similarly to traditional die punches. Unlike standard flat blades, these tools feature defined cutting edges in precise shapes: round, oval, square, or custom geometries. This design enables efficient creation of holes, slots, and profiles in soft-to-semi-rigid substrates.
Industries requiring exact, repeatable cutting – particularly packaging, foam processing, leather cutting, rubber fabrication, and textile production – routinely deploy punch knives. Manufacturers utilize them either as manual tools or integrated within automated die-cutting systems, often customizing the cutting edge geometry to match exact application specifications.
