Ice Hardened blades are cryogenically treated resulting in a metal cutting blade that is more consistently hard throughout. Heavy-duty demolition blade is designed to reduce bending and breaking. Optimized tooth form for the longest life and maximum durability. Tough Neck ribs strengthen the blade tang and minimize breakage. Grid Iron honeycomb pattern throughout body of blade increases blade rigidity to resist blade buckling. Ideal for making tough, straight cuts.
