Benefits of LazerEdge EverSharp blades: Blades stay sharp longer Less mower maintenance Healthier, greener lawns Increased fuel efficiency LaserEdge® is the only commercial mowing blade that sharpens itself. Utilizing EverSharp™ technology, these hardened steel blades deliver superior performance and get sharper during use, resulting in minimal maintenance and maximum profitability for landscaping professionals. EverSharp’s advanced surface-engineered edge is applied to the blade's underside. As the blade is utilized, the base blade material begins to wear away, exposing a new LaserEdge® blade edge, which is harder and more wear-resistant than the original cutting edge. There will be no more downtime to sharpen blades, no more blade sharpening expenses, and no more fuel usage increase due to dull blades. There will be only uptime and increased profits. LaserEdge can save your operation money and give you the most well-manicured lawn in the neighborhood or around town.

High-quality, hardened steel blades equipped with the LaserEdge Eversharp technology on their cutting edges have demonstrated their toughness and durability in field tests, even in the most abrasive conditions. In the test, a brand new mower blade had LaserEdge technology applied on one cutting edge and was left untreated on the other edge. After putting the blade to work for 50 hours, the results were clear. The LaserEdge cutting edge was still sharp, and the untreated side was dulled and worn away. #lazeredgeblades
