For years, auto glass technicians have been grinding their blades to create a smooth radius on the back. While it makes for easier cuts by reducing resistance, it can also weaken the blade two ways if done incorrectly: First, by removing too much material making it structurally weaker. Second, by adding too much heat when thinning the blade, which can temper the steel, making it softer. This means technicians may spend extra time preparing their blades and having to contend with more breakages. What we've done is create the conical shape with our specially designed machines before the heat treatment process, providing both excellent performance and strength which saves technicians valuable time and ultimately money.
We added this new radius grind to our unique serration design with its small, leading edge points that pierce the urethane for an easier pull during cutting. With only small serration points touching the glass, the majority of the blade stays sharper, longer. Finally, to keep the strength of the extremely thin radius serrated blade, we added a center rib for overall strength. The combination of our thin design and unique serrations provides less cutting resistance than any other blade in the industry.
