Abstract
A stapler selectively uses enhanced leverage to break a glue bond of a staple to separate the staple from a rack of staples in the stapler. The staple does not press a working surface during this operating stage. The extra leverage stage occurs through a minority of total handle travel, preferably via a pivoting lever linked to the striker at one end and the opposite end traversing between inner spaced apart ribs underneath the handle. A remaining non-leveraged handle travel stage ejects a staple out from the stapler body against a working surface. A track supports staples from an underside of the top of the staples. The track includes an outward extending bottom support for at least one staple on the track to prevent rotation of a short rack of staples.
