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.

This 204S sickle scaler end (left side) is used for supragingival calculus removal in the interdental spaces of the molar region. Its NANOPAL coating is a harder surface for a longer-lasting edge. The insert is the part that wears, so it is exchanged on its own and the handle stays.
