Knife, in particular for slicers

A blade for machines for cutting elastic products into slices, the blade comprising:

• a plate-shaped base body having a rotation axis, a rear cutting surface, which forms a part of a blade rear side of the plate-shaped base body, and a front cutting surface, which forms a part of a blade front side, wherein the rear cutting surface and the front cutting surface meet in a continuous cutting edge, wherein
• the blade rear side extends axially outwards from a cutting plane, defined by the cutting edge on a front side of the plate-shaped base body,
• the rear cutting surface is inclined relative to the cutting plane at a cutting angle,
• the rear cutting surface is positioned adjacent to a pressing surface, wherein a portion of the pressing surface extends on the blade rear side at a pressing angle relative to the cutting plane which is smaller than the cutting angle,
• at least one recess is formed only in the pressing surface on the blade rear side, with a radially outer end of the at least one recess terminating distant from the cutting edge, and a radially inner end of the at least one recess terminating radially outward from a radially inner end of the pressing surface,
• wherein a size and/or a shape of a cross-sectional surface of the at least one recess transverse to the cutting plane varies in a direction in which the cutting edge extends, wherein a position of the at least one recess relative to the cutting edge varies in the direction in which the cutting edge extends, and
• the at least one recess extends only along a part of a length of the cutting edge, or the cutting edge is a finite cutting edge and the at least one recess ends at a distance before a beginning and/or before an end of the cutting edge.
