What is the difference between SF1, SF3 and SF4 .25 inch staples?

I had the same question and just found the answer on Swingline's website. SF1 are standard staples in a "full strip," i.e., 210 staples per strip. A full strip is about 4 inches (10.16 cm) long. "Standard" staples means they're made of Swingline's standard quality of metal wire.SF4 are also full-strip staples, exactly the same size as SF1, but are "premium" because they're made of a stronger wire (specifically, with greater tensile strength), which Swingline says results in 75% fewer misformed staples.SF3 are exactly the same as SF4, except they are "half strip" staples, i.e., 105 staples per strip. A half strip is about 2 inches (5 cm) long. There's no difference between any of the dimensions of the individual staples. They all have a .25-inch "leg," which means they can hold about 20 to 25 pages, depending on the type of paper.The Swingline FAQ is at http://www.swingline.com/swingline/us/us/s/3227/stapler-staples-faq.aspx
