1. A stationary cutting blade for a hair clipping device, comprising:

  • a base body; and

    a plurality of coined cutting teeth which are spaced apart from each other and arranged on a front side of the base body and each extend parallel to a longitudinal axis of the stationary cutting blade;

    wherein the stationary cutting blade is a full metal cutting blade and the base body has a first thickness (t1), said first thickness (t1) being measured between a top side and a bottom side of the base body along a transverse axis perpendicular to the longitudinal axis, wherein the cutting teeth have a second thickness (t2) measured parallel to the transverse axis, wherein a thickness ratio between the first and the second thickness (t1/t2) is larger than 1.1;

    wherein each of the plurality of cutting teeth has a substantially wedge-shaped cross-section with a top face, a bottom face and two opposing lateral faces running in between the top and the bottom face;

    wherein a cutting edge that is defined at the intersection between the top face and an upper section of one of the lateral faces has a scissor angle (α

    ), which is defined between the cutting edge and an imaginary plane that is parallel to the longitudinal axis and the transverse axis, and a wedge angle (γ

    ), which is defined between said upper section of the one of the lateral faces and the top face;

    wherein a sum of the scissor angle (α

    ) and the wedge angle (γ

    ) is smaller than 70°
