发明名称 Darts
摘要 A dart is described having a shaft to carry the flight, with a slot opening diametrically through the thickness of the shaft so that the flight can be deformed to a flat condition and pushed laterally through the slot, the extreme end of the shaft behind the flight being closed and pointed or rounded to provide a deflection surface in the event of contact by a further dart.
