FIELD: plastic working of metal, possibly manufacture of nails.
SUBSTANCE: method comprises steps of clamping wire in die halves and deforming it for forming head with smooth end surface; then finally working head by means of finishing punch in order to form rhomb-like notches onto smooth end surface of head or to form lengthwise grooves on smooth end surface of head and(or) on its supporting surface. Said notches and grooves are formed while arranging large diagonal of rhomb of notch or lengthwise grooves in direction of less size of cross section of head with smooth end surface; said less cross section is formed due to pressing out part of wire metal into parting between die halves.
EFFECT: enhanced accuracy of articles.
