Abstract
The grinding body has a spheroidal tetrahedron like shape. In one version, on at least one of the faces of the grinding body there is a spot (1). The spot may be flat convex or concave. A short cylinder (5) with a flat top (6) can be made on one of the faces of the body. In another version parts of a cylinder (9) are performed through three of the vertices and on three of the faces. In another version at least one of the vertices of the tetrahedron is cut flat. In another version the flat cut vertex is round more or less concave. In another version a short cylinder or a short prism with flat tops is made on the flat cut vertex. In another version a peripheral ring (12, 13, 14) is made through three of the vertices and over three of the faces.

AMENDED CLAIMS
received by the International Bureau on 30 July 2012 (30.07.2012)
1 (new). A grinding body with a spheroidal tetrahedron-like shape, characterized in that the three equally long arcs of the edges (3), going out of the same vertex (4), have lengths equal with or different from the arcs of the other three edges, which are also of equal length between them and on at least one of the faces of the body there is a flat spot (1) or a cylinder of small height (5) or a or a short prism, each one having a flat top (6).
2. A grinding body according to Claim 1, characterized in that the arcs of the edges (3) of the body are parts of a circle or of another geometrical curve.
3. A grinding body according to Claims 1 and 2, characterized in that the centres of radii of the arcs of the edges (3) may be situated inside or outside the vertices (4) of the tetrahedron.
4. A grinding body according to Claim 1, characterized in that at least one of the vertices (4) of the body is cut flat (10) with the plane perpendicular or at an angle to the axis of the tetrahedron.
5. A grinding body according to Claims 1 and 4, characterized in that on the flat cut vertex (10) of the body a cylinder of small height or a prism with a triangle-like cross section is formed, each one having a flat top.
6. A grinding body according to Claims 1, 4 and 5, characterized in that the flat cut vertex ( 10) of the body is more or less round-concave (11).
7. A grinding body according to Claim 1, characterized in that the spot (1) has a circular or other shape and is flat or round more or less convex (7) or concave (8) to the face (2) on which it is situated.
8 (new). A grinding body with a spheroidal tetrahedron-like shape, characterized in that through three of the vertices (4) and along three of the faces (2) surrounding are formed parts of a cylinder (9) or a peripheral ring (12, 13 H 14). 9
9. A grinding body according to Claim 8, characterized in that the peripheral ring
(12) has a circle-like cross section, more or less convex.
10. A grinding body according to Claim 8, characterized in that the peripheral ring
(13) has a triangle-like cross section, more or less convex.
11. A grinding body according to Claim 8, characterized in that the peripheral ring
(14) has a rectangle-like cross section, more or less convex.
12. A grinding body according to Claims 1 to 11, characterized in that all edges and vertices of the body may be rounded on part of a circle, a spiral or of another geometrical curve.
