TrueFit™ Technology is an advanced sensor-based technology system which has measured over 2.8 million data points for pinch force in the finger and pressure applied to the tooth when scaling. HuFriedyGroup pioneered TrueFit Technology to address the need for scientific evidence in ergonomics.
The durable metal handle, which features a recessed double-helix texture, is designed for optimal tactile sensitivity and to reduces tactile fatigue.
This may alleviate hand fatigue and injury risk due to repetitive motions.5,6,7,8
The silicone grip has been extended by 30%, which can provide a secure and nimble grasp while using the instrument. The geometric pattern is specifically designed for maximized grip in all directions.
Harmony™ Scalers and Curettes may increase patient comfort, while reducing clinician fatigue because it requires less pressure to the tooth when scaling.
Due to the round shape of the handle and the smooth transition to the functional shank, you can comfortably maneuver and roll the scaler. With over 2.8 million data points measured, this handle was designed to easily adapt to your individual grasp.
Harmony scalers are available in over 95 instrument designs allowing customization of procedural setups to meet your unique scaling preferences.
EverEdge™ 2.0 working ends are 72% sharper2 than the next leading competitor allowing clinicians to efficiently remove calculus. Sharp scalers require less pressure to do the same amount of work, creating a more comfortable experience for you and your patients.

Independent testing was conducted by CATRA, a specialized blade laboratory. They evaluated Hu-Friedy EverEdge scalers alongside four competitors' instruments.
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.
EverEdge scalers are sharp...EverEdge 2.0 scalers are even sharper. Less force means easier, more comfortable scaling for the clinician and patient.
EverEdge 2.0 uses a new, optimized heat control process in order to maintain the hard, sharp edge.
This heat control, plus several manufacturing intricacies in Hu-Friedy's proprietary process, provide the durability needed for effective procedures and continued use.
Hu-Friedy has invested in a custom blade evaluation system to ensure clinicians are receiving the sharpest possible instruments. Blades from every batch of EverEdge 2.0 are tested right off the factory line to confirm that the sharpness value remains in our target range, averaging 5 newtons of force required to cut the test material.
Since the special characteristics of EverEdge 2.0 scalers are present throughout the entire blade, you are able to sharpen them at any point to extend their useful life while maintaining the integrity of the metal. If you don't want to sharpen, dispose of the instrument through Environdent and use a new scaler. Either way, the choice is yours.
Every time I used this scaler, it felt like the first time it was used. NICE & SHARP! Russell Harms, RDH, RSDH
