There have been few changes to the thumbtack since 1904, when Johann Kirsten placed a flat head upon the original Edwin Moore 1900 push pin design. Now, the design has been completely revolutionised by Mark Weiser with Pon, a pin that does not puncture the paper you are putting up.
The Pon is an ingenius hybrid of the paperclip and thumbtack that sees a coil hug the sheet you wish to suspend, whilst a protruding pin enters the wall. Beyond it’s simplicity, the pon is made with a heat treated stainless steel that purportedly allows it spring back to it’s original coil even after significant distress.
Goodbye pin punctured and torn posters. Hello, everyday design marvelling.
Is this the pinnacle of good design? (Pon intended).
