Each blade measures 21 inches long by 2-1\/4 inches wide and features a 59\/64\" by 11\/16\" center hole with a medium lift and notched design. These blades are crafted from Sunbelt’s patented XHT (Xtreme Hardness \u0026amp; Toughness) Marbain® heat-treated steel, which has been independently tested to provide superior hardness and resistance to bending and impact damage. This advanced treatment ensures a cutting edge that remains sharper for longer, with XHT blades being approximately 25% to 40% harder than standard lawnmower blades. They offer the tightest tolerances when compared to original equipment blades across all makes.
