About the Material
Jasper is a dense natural stone with a microcrystalline quartz structure (Cryptocrystalline Quartz). It provides smooth, controlled polishing and a clean refined edge.
Natural stones do not have a fixed grit rating, but jasper typically performs in the range of approximately 8000–10000 JIS, depending on density and lapping.
Steel Compatibility
Suitable for carbon, stainless, Damascus, high-speed, and powder steels up to 63 HRC.
