A Blot’s Arrow Perforator made from nickel plated base metal. The tip of the perforator is flat and has no locking mechanism. The steel sprung handle in its resting position keeps the blades closed whilst penetrating the foetal skull.

The blades are opened by applying pressure to the handle which widens the perforation and allows subsequent collapse of the skull so as to remove the dead foetus in cases of arrested labour due to cephalopelvic disproportion. In excellent condition throughout noting minima loss of plating.
