Each RazorTOOTH Saw® blade goes through four manufacturing processes for maximum durability and hardness, friction reduction, and making extremely fast and efficient cutting. Saw blade with triple-ground impulse hardened teeth for 2.5x more material removed per stroke. The three-sided razor teeth offer efficient cuts. This steel blade contains more carbon, which means harder steel, allowing the blade to stay sharper longer. The chrome-plated blade reduces friction and improves efficiency. Replaceable, curved, taper-ground folding blade. Ergonomically designed, comfortable, and co-molded handle.
