Clean slicing and precision control define the Jig Saw Blades, Knife Edge, Polystyrene, designed specifically for cutting soft plastics, foam, and insulation materials without melting or tearing. The sharpened knife-edge blade glides smoothly through polystyrene and similar substrates, producing accurate, smooth edges with minimal friction. Constructed from durable steel, it maintains rigidity and sharpness for consistent, repeatable performance. The flexible body allows easy maneuvering along curves and contours. Compatible with most jig saws, these blades are ideal for marine insulation, modeling, and metric fabrication applications requiring delicate, controlled cuts.
