A useful model refers to agricultural engineering, in particular, to the details of the working organs of cultivators and sowing complexes.The arched paw contains V-shaped wings with a toe and chest with a shank, two holes located on the axis of symmetry of the shank, the lateral edges of which are smoothly interfaced with the rear wings of the wings, the center of the bending radius of the chest and shank is located on the vertical passing through the toe of the paw, in that the paw is made of sprinkled spring steel 65G with a thickness of 6-8 mm and is made of a whole-stamped with heat treatment, while the tail part has a hardness of HRC30 units, and the wings and the cutting edge have a hardness of HRC50 p, distance between the centers of holes paw directly proportional to the distance between the centers of seats at the front of the working organ, the angle depends on the chopping conducted technical measures and is 14 ° -26 °, the wings of the cutting edge are made with a bottom sharpening at an angle of 12 ° -18 ° relative to the cross section of the wing of the cutting edge, the nose part being made without sharpening, the thickness of the nose corresponds to the thickness of the paw, the hard-alloy material is welded on the outside of the cutting edge, each hole is made in the form of a square with a chamfer under a countersunk bolt, the angle of inclination of the shank corresponds to the angle of inclination of the post of the tool, the shape of the rear wall of the shank corresponds to the shape of the cross section of the work post his body.The technical result is an increase in the duration of operation of the lancet paw in carrying out various agrotechnical measures with the effect of self-sharpening.Полезная модель относится к сельскохозяйственному машиностроению, в частности к деталям рабочих органов культиваторов и посевных комплексов.Стрельчатая лапа содержит V-образно расположенные крылья с носком и грудь с хвостовиком, два отверстия, размещенные
