A shear blade is for a portable hydraulic cutting device having a blade body. The blade body has assembly and cutting regions, with a cutting edge in the cutting region. A contact surface is on one side of the cutting edge for an additional shear blade. An outer surface on the other side of the cutting edge acts on the object to be cut. A first surface portion of the outer surface extends away from the cutting edge along an orthogonal, which meets the contact surface at the cutting edge, or at an acute angle α relative to the orthogonal. A second surface portion connects to the first surface portion at an acute angle β to the orthogonal. A third surface portion connects to the second surface portion at an acute angle γ to the orthogonal. Angle α is smaller than angle β, which is smaller than angle γ.
