Abstract
A hole punch includes a base and a handle assembly to actuate a punch pin. The base may include a housing enclosing a punch head, and the housing may include an opening where the handle assembly is adapted to be recessed within the opening. The handle assembly may include a first linkage and a second linkage, each pivotally coupled to the base, and a third linkage pivotally coupled to both the first and second linkages, where the third linkage is arranged to move substantially parallel to the base. The first linkage may be substantially parallel to the second linkage when the punch pin is in a rest position, and the second linkage may be configured to nest within the first linkage when the punch pin is in a deployed position.
