In reality two completely different filling systems are called ''hatchet filler'', as they were given this name by their respective manufacturers. The first is the one used by [[Holland]] from 1908 to 1912. The filling always involved the use of a pressure bar placed at a slit, except that in this case the slit was left open on one side, while on the other side a 'P' shaped lever was placed.
