Furthermore, this can be a material-specific and dependent on geometric dimensions resistance moment are lowered, which precludes bending of the blade about a bending axis in the cutting plane and perpendicular to the cutting direction.
- the passage opening may be formed as a slot, which preferably extends in the cutting direction.
- the blade of the blade can be straight.
- the cutting edge has a curved course.
- the cutting edge can be sickle-shaped and preferably extend concavely into the blade body. Similar to a serrated edge of a cutting edge, the cutting capacity of the cutting edge can also be increased here. As a result of their concave arrangement, the blade can be protected in the blade body.
- the cutting edge is mirror-symmetrical with respect to its cutting direction and / or its cutting plane.
- the cutting edge can be arranged with respect to its longitudinal extent transverse and mirror-symmetrical to the cutting direction in a central region of the rear narrow side.
- the center area of the narrow side with the cutting edge can be offset by an amount opposite to the cutting direction of the rear Narrow side offset in the blade body into it to be arranged.

- the blade can be constructed mirror-symmetrically with respect to a central longitudinal axis running in the cutting direction.
- the cutting portion may have a substantially triangular shape, wherein a rear side in the cutting direction triangle side forms the narrow side with the cutting edge, the other two sides of the triangle converge to the holding part and the through hole is arranged in the triangle.
- the holding portion may extend tongue-like from the cutting portion opposite to the cutting direction. This allows the blade to have a substantially Y-shaped outline.
- the blade and spacer element can have a similar outline shape. It can blade and spacer element in the working position of the spacer element except for the rear narrow side of the blade with the cutting edge over each other and flat against each other applied to the gouging machine or be arranged in the same recording. In this case, the blade can only have the additional central area with cutting edge.

As a result, the cutting edge of the blade shielded and thus the handling of the blade can be made safe. Due to the eccentric arrangement of the cutting edge, the same can be moved correspondingly in two different areas above the substrate.
- the planing off of protrusions can also take place in three cutting steps, in which the blade cuts the supernatants to residual overhangs in a first step in the doctoring position.
- the blade in the investment position, but with the cutting edge spaced apart from the ground, continue to cut off the remaining projections or planing off.
- the blade can be used turned by 180 ° in the installation position so that its cutting edge rests on the ground or only slightly from it is spaced, so that the remaining projections can be completely planed. It can also be the spacer element used only when higher residual overhangs than those achievable by the off-center blade are desired.
- the cutting edge is preferably arranged parallel to the side surfaces.
- the off-center cutting edge may be spaced a distance a from the blade side surface and at a distance b from the other blade side surface.
