In realtà vengono chiamati ''hatchet filler'' di due sistemi di caricamento completamente diversi fra loro, a cui però venne dato questo nome dai rispettivi produttori. Il primo è quello usato dalla [[Holland]] dal 1908 al 1912; il caricamento prevedeva sempre l'uso di una barra di pressione posta in corrispondenza di una fenditura, soltanto che in questo caso la fenditura era lasciata aperta da una parte, mentre dall'altra veniva disposta una leva a forma di "P".

La leva era incernierata su uno dei suoi estremi (il gambo della "P") in corrispondenza della fine della fenditura, e rientrava con la parte sporgente all'interno del corpo della penna, sul fondo della stessa. Per il caricamento la leva veniva estratta e ribaltata di 180°, per poter andare a premere sulla [[barra di pressione]] usando la parte sporgente; una volta portata la leva in posizione di pressione in sostanza il meccanismo diventa analogo al ''[[crescent filler]]'', con il vantaggio del non avere sezioni sporgenti (ma con lo svantaggio di una certa fragilità e complessità meccanica).

Filling systems

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.

The lever was hinged on one of its extremes (the stem of the "P") at the end of the slit, and returned with the protruding part inside the body of the pen, on the bottom of the same.
