Punched precisely for 4-1/2 Race or 4-1/2 Race XS nails and requiring little filing to reduce the head of the nail.
Size 2x0 and 0 are punched for 6 nails; sizes 1 is punched for 8 nails.
New Material: Now made with a higher carbon steel. Because higher carbon content can increase the chances for breakage, if the shoes are quenched while red hot, Kerckhaert advises "air cooling" of the shoes.
