For the sharpest and most polished edge

The SJ-200 waterstone is designed for craftspeople and enthusiasts who demand superior sharpness and a mirror-polished edge. The stone removes only minimal amounts of steel and is therefore perfect for fine honing of tools, knives, scissors and woodcarving tools. The result is a surface that almost never requires additional polishing on the leather honing wheel.

Limited cutting performance – mirror-polished finish

As the SJ-200 has a very fine grain structure, its cutting performance is intentionally limited. This means the stone is not suited to coarse shaping or repairing the edge, but solely to the final polishing stage. If a tool needs to be shaped or corrected, this should be done on a coarser grinding wheel before finishing with the SJ-200 for the final result.

Long service life and simple maintenance

The Japanese waterstone has a special composition that ensures long-lasting durability. To preserve the surface, the stone should be cleaned regularly to remove fine steel particles. This can be done with the fine side of the Tormek SP-650 Stone Grader or the coarse side of a sponge. Do not use the coarse side of the stone grader directly on the SJ-200, as this may damage the stone.

No, the stone is intended solely for fine honing. Coarse shaping should be carried out with a different, coarser grinding wheel.

How do I maintain the stone?
Clean the surface with the fine side of the Tormek SP-650 Stone Grader or the coarse side of a sponge. Avoid using the coarse side of the stone grader directly on the SJ-200.

Yes, it is compatible with the Tormek T-4, Tormek T-3 and earlier models with a 200 mm grinding wheel.

Do I need to use the leather honing wheel after sharpening?
