Shapton GlassStone (GS) Series HC Stones
From Lee Valley
Size: Shapton GlassStone HC Stone 1.84µ 8000x
This innovative design uses tempered float glass as a foundation for each stone, giving it a degree of dimensional stability and strength while ensuring that all the abrasive is usable.
Overall stone dimensions are 210mm × 70mm × 11mm (8 1/4" × 2 3/4" × 7/16") with 5mm of usable abrasive thickness. Each stone weighs about 14 oz (400g). Use with the Shapton stone holder or field holder for a solid base that holds the stone at a good working height.
The GS series has the largest range of grits and will appeal to technical sharpeners who can build a sharpening regimen that meets the needs of any blade. For forge-welded composite steel blades, Shapton recommends these HC-designated 4000x, 6000x and 8000x stones that use an abrasive agent best suited for those blades.
The HR stones are the regular stones (sold separately).
