Vintage natural Arkansas stone for ultra-fine finishing, edge refinement, and mirror polishing.
Natural stone
Made from natural novaculite quarried and finished in the USA. Hard Black is one of the hardest and finest grades of Arkansas stone.
Finish
Designed for final edge refinement and mirror polishing, producing an exceptionally fine and highly refined finish.
Durability
Dense Hard Black novaculite wears exceptionally slowly, making it a long-lasting finishing stone designed for years of use.
Performance
Norton Hard Black Translucent combines ultra-fine abrasive action with a burnishing effect. In addition to refining the edge, it helps compress and polish the surface for a smooth final finish.
Its dense natural structure makes it especially suitable for the final stages of sharpening where maximum refinement and polish are required.
Lubrication
Hard Black is traditionally used as an oil stone, providing smooth and controlled finishing during the final sharpening stages.
Versatility
The stone can also be used with sharpening slurries and polishing compounds to adjust its finishing characteristics.
