Abstract

The dart for a blow pipe comprises a rod with one end pointed. On this, are mounted two discs of equal diameter and separated from each other. This spacing is between d and 2.5d, where d is the disc diameter. The discs are moulded and have a greater thickness in the centre than at the periphery. Each disc is made of two rigid parts between which is a circular piece or pads thinner than the two pieces, and protruding from the outside of them. The dart gives accuracy of flight.
