Design Notes
Nanopal® coating: the black crystalline nano-coating raises surface hardness to 4,500 Vickers — the highly tempered cutting edge stays aggressive and sharp far longer and does not need resharpening after each curettage, while the scratch-resistant black surface is easy to clean and prevents light reflections.
