WHY DO SOME INSTRUMENTS GET SHARPER AFTER SEVERAL USES? When there is a spike in sharpness, that is due to the burr formation on the product. A burr is a small flap of metal that actually covers the instrument’s blade. Burr formations occur when the finishing step is done too quickly — an indication of poor process control. EverEdge 2.0 scalers do not have a burr formation due to our refined process and techniques.
WHO TESTED THE INSTRUMENTS? Independent testing was conducted by CATRA, a specialized blade laboratory. They evaluated Hu-Friedy EverEdge scalers alongside four competitors’ instruments. HOW WERE THE INSTRUMENTS TESTED? The blade of each instrument was tested by repeatedly pushing it into a specially calibrated silicone test strip. The amount of force required to push the blade into the test media was measured in Newtons, a common international unit used to measure tension and shear force. The less force required to penetrate the media indicates a sharper blade. The blades of each instrument were also subjected to multiple strokes on the same calibrated test strip to simulate wear. These repeated strokes will begin to reduce the sharpness of the blade and therefore require more force to enter the test strip. After a predetermined amount of strokes is applied, the force to make the final cut is measured to determine the sharpness durability of the blade.
