SVST ALU-OXIDE STONE
SVST ALU-OXIDE STONE
Bonded hard stones made by fusing the mineral bauxite that "sand and grind" steel, but not as aggressively as diamond stones.
The SVST Pocket Stone - two edge tools in one! The top-quality Aluminum Oxide stone has a 220 grit diamond abrasive on the other side. Diamond for rough filing, and aluminum oxide for fine tuning. The Pocket stone measures 10cm X 2cm X 0.5cm.
