The Irwin Marathon blade is designed especially for deck building, where carbide-tipped teeth and a thin kerf combine for fast, clean cuts through treated lumber. The alternate top bevel (ATB) grind with 20-degree hook angle provides aggressive cutting action, while heat vents reduce build-up and warping for truer cuts over the life of the blade.
