The blade is made of heat-treated stainless steel that has one or two sharp edges for resurfacing ice, such as at an ice rink with an ice resurfacing machine. The preferred material is stainless steel. The blade lasts four times longer than a conventional blade, reducing the sharpening interval and reducing the cost of removal, replacement, shipping, and re-sharpening. Reduced maintenance lowers the chance that a worker will be injured during maintenance activities. The life of the blade is about 15 years compared to one year for conventional bladed. It does not corrode during storage. Because the blade is sharper and stronger than conventional ice resurfacing blades, it provides a flatter and smoother finished ice surface than conventionally available. The improved blade allows the ice to be resurfaced more quickly by allowing deeper cuts and faster operation of the resurfacing machine itself. |
