Overview
The S SATC diamond sharpening stone is a two-sided stone with 400 and 1000 grit diamond surfaces in one piece, weighing 1.9 pounds.
Despite being filed under Chisels here, this is a sharpening stone, not a chisel. The two grits let a single stone handle both initial edge shaping at 400 grit and finer honing at 1000 grit without swapping stones, and diamond abrasive holds its cutting speed longer than natural or ceramic stones while needing no oil to work.
- Two-sided stone
- 400 and 1000 diamond grit
- 1.9 lb weight
- Single piece, no oil needed
Who it's for
Suits anyone maintaining knives, chisels or plane blades who wants one stone for both coarse and fine sharpening steps. Not a finishing stone for mirror-polish edges, since 1000 grit is a mid-range finish rather than an ultra-fine one.
Strengths and trade-offs
Drawn from this product's published specifications.
- Two grits in one stone for dual-step sharpening
- Diamond abrasive cuts faster, no oil needed
- 1000 grit is mid-range, not a polishing finish
- Miscategorized as a chisel in this catalog
Performance notes
Diamond abrasive cuts steel faster and stays flat longer than natural stones, and the 400/1000 grit split covers the two steps most sharpening jobs need: reshaping a dulled or damaged edge, then refining it. At 1.9 pounds the stone has enough mass to stay stable on a bench during use.
