A hoe comprises the elements joined between each other, a handle, a cramp, a cutting plate, a wedge, which are rigidly fixed by a rivet, an additional plate and electric welding. The plane of the cutting plate is arranged at an angle of 66÷75° to the longitudinal axis of the handle, and the cutter edge of the plate looks like an open rectangle and is sharpened at an angle of 5÷18° from the outer side. |
