LM Sharp Diamond™ Instruments — Sharpen-Free Efficiency Saves You Time
Stop sharpening — start scaling.
LM Sharp Diamond™ instruments feature a unique PVD micro-coating fused with a carbide-enhanced alloy, making them completely sharpen-free. You’ll enjoy consistently sharp edges and effortless scaling for the full lifespan of the instrument — no maintenance required.
- 100% Sharpen-Free — Never touch a stone again.
- 80% Less Wear than leading Hu-Friedy instruments (independent wear-test verified).
- Precision-Formed Tips that stay sharp and efficient from the first patient to the last.
- Lighter Pressure, Less Fatigue — reduced hand strain and smoother instrumentation through superior ergonomics.
Spend your time on patients — not on sharpening.
DuraGradeMax® Stainless Steel — Built Stronger
For hygienists who prefer traditional steel instruments (comparable to Hu-Friedy stainless steel instruments), or for hygienists who prefer sharpening their own instruments, LM’s DuraGradeMax® line offers a new standard in performance and longevity.
Our proprietary alloy delivers superior hardness, wear resistance, and corrosion immunity compared to standard Hu-Friedy stainless steel.
- Exceptional Strength & Rigidity for controlled scaling.
- Resharpenable Design — maintains edge integrity through repeated use.
- Optimized Alloy Composition for durability and tactile sensitivity.
- Precision Machined Edges ensure consistent cutting performance.
Stronger steel. Sharper edges. Longer lifespan.
Superior Ergonomics for Every Hygienist
LM’s ErgoSense™ handles feature medical-grade silicone grips with a 14 mm diameter — scientifically proven to reduce pinch force and hand fatigue during repetitive scaling.
Every instrument is color-coded for easy identification, helping hygienists work faster and with better posture.
- Lightweight alloy core for tactile feedback
- Non-slip silicone surface for comfort and control
- Vibrant color system for quick recognition
Ergonomics isn’t an upgrade — it’s a standard.
