Disadvantages of Kielland and Barton forceps are described. A trial of K.B.L. forceps was undertaken in transverse and posterior positions of the fetal head. It was concluded that these forceps are easier to apply than Kielland forceps. Rotation of the head is easier, and they are the equal of Kiellands as tractors, with the advantage of causing less marking of the fetal head than either Kielland or Barton forceps.
