Pearl P4™ Porcelain Reactor™ blades are engineered with ADM™ (Advanced Diamond Matrix) technology. ADM™ is a unique diamond patterning and layering technology that ensures an optimal cutting surfaces at all times. ADM™ outperforms traditional diamond bonds in both cutting speed and longevity. The P4™ Porcelain Reactor™ Blade excels at cutting hard and dense materials quickly and cleanly. The P4™ also features a thicker steel core for less deflection. This design produces straighter, smoother cuts without sacrificing cutting speed.
