Indestructible-Binder-01.jpg

When I was a kid, I was very hard on school supplies, and I remember dreaming of indestructible versions of all my gear—Kevlar backpacks and, particularly, sheet aluminum binders with continuous hinges. These days, you can actually buy such binders, but they are relatively expensive. So why not make your own? Instructables user cowscankill did, with a salvaged snap-ring mechanism and riveted leather hinges. I want one.
