EOU, sorry for skipping any introduction to Tormek.
Tormek grinders are Swedish water cooled machines for sharpening edge tools. It is quite expensive, but high quality standard grinder. Each tool has its own grinding jig which operates on the so called universal support bar. This guarantees consistent sharpening angle.
The knife jig can operate in both grinding directions, towards the edge and away from the edge. Grinding towards the edge is more frequently used because it is more aggressive and therefore quicker. Grinding away from the edge gives larger burr which can be detected sooner, assuming we check it often during sharpening.
To avoid mounting the knife into the knife jig some Tormekers developed platforms for free hand sharpening. In the attached picture you can see my homemade flat platform which guarantees the same bevel angle for sharpening in both directions. The smaller flat platform serves for honing.
