I do genealogy for both sides of the family. I depend on my Swingline
heavy duty stapler to keep all my information in order. I print genealogies for all the kids, as they marry, so they can keep track of their families. I staple bind these with my Swingline.
It has been so reliable, easy to use, easy to refill, and relatively problem free. When you need to depend on something, depend on Swingline!
