That other staple-less stapler: the paperclip

Although seen by some as a bit of a design cliche, the humble paper clip is one of the more instructive examples of an eco-product:
• solves a problem with panache (and without adding to any larger problem)
• purpose is swiftly understood (no manuals required)
• remains useful across varied linguistic, cultural. racial, social and economic divides
• single material (no contaminating components or composites, assuming it's a plain, polished aluminium version!)
• made of a readily recyclable material
• can be re-used (over and over and over....)
• simple, elegant design
• aesthetically pleasing
• can used for many other purposes
• lightweight
• requires no other equipment or tool to be used
• inexpensive
• timeless (well, for the past 100 years or so, anyhow)
If only all products could say the same thing! It's not perfect but it does better than most. ::History of the paperclip [by WM]
