LM-SHARP DIAMOND - Sharpen-Free Perio


  • Combination of a Universal Curette, Gracey 1/2 and Gracey 7/8
  • For both concave and convex surfaces
  • For removal of supra- and subgingival calculus
  • Distal and mesial surfaces of the same interdental space can be treated with the same instrument head
  • Suitable for both vertical and horizontal techniques


3-in-1. Save money while freeing up space in tray setups and increasing clinical efficiency. With the Anterior Dual Gracey (Syntette), clinicians have the option to replace current Universal Curettes and Graceys 1/2 and 7/8, with a single instrument. The Dual Gracey combines the dual-edged tip efficiency of a universal curette with the complex shank angles and area-specific tip placement capabilities of the Gracey 1/2 and Gracey 7/8 in one instrument. Please click on the video tab to watch this unique instrument in action.

Both distal and mesial surfaces of the same interdental space can be treated with the same instrument head - without the need to flip or switch instruments. Simply tilt the instrument one way or the other to activate the cutting edge. This instrument is specifically designed for the removal of supra and subgingival calculus in anterior and premolar areas and for both concave and convex surfaces.  Suitable for both vertical and horizontal techniques.


  • 100% sharpen-free means effective calculus removal without the need to sharpen
  • No more worrying about altered blade tips or angles
  • Effortless, worry-free scaling
  • Highest-rated ergonomic handle minimizes hand fatigue and potential musculoskeletal disorders
  • Full control and improved tactile sensitivity
  • Savings of time & money
  • Improved productivity & clinical results


The dark tips of SharpDiamond instruments look different because they are different. A diamond-like micromembrane enhances the already superior wear-resistance of LM's proprietary alloy base to produce completely 100% sharpen-free scalers and curettes. 

In the final phase of precision-honing, LM’s ultra-modern PVD coating process follows the exact geometric planes of the instrument to ensure flawlessly sharp tips and the longest-wearing edges unmatched by anything else in the field.


Hardness contributes to the durability of the instrument. LM Sharp Diamond™ reach hardness of over 63 on Rockwell scale.

Because SharpDiamond instrument tips maintain factory edges and remain sharp for the duration of its lifespan, clinicians can stop worrying about all the issues related to sharpening, once and for all.

And with unparalleled wear-resistant edges that effortlessly shave off every last bit of calculus, less force is needed when scaling. The result is easier, more comfortable scaling for both the clinician and patient and uncompromising clinical results.


Ergonomics and innovation have been the guiding principles of design at LM since the 1980's. The ErgoSense handle is a culmination of intense research and product development in close cooperation with dental clinicians and professionals. Feel the difference in your grip both while working and at the end of your day. 

Lightweight and thicker contoured, ErgoSense handles are ergonomically designed to offer the most comfortable grip and exceptional control even in wet environments. 

To ensure optimal rigidity and tactile feedback, LM’s proprietary metal core runs through from tip to tip. The durable elasticity of medical-grade silicone with colour-coded "at-a-glance" identification, has been tested to remain unchanged through 2,000 autoclave cycles.
