The thumbtack and the paper clip haven't seen much improvement since they were introduced to the office supply world -- but that's because they haven't needed any. So it's surprising how useful the two can be when merged into one tool called the Pinclip that lets you hand documents or photos without having to pierce them full of holes.
It's a clever bit of synergy, but unfortunately not marring your photos with holes comes with a steep price tag: a set of three Pinclips will cost you around six bucks. But, if you're handy with a pair of pliers and a file, a bit of bending and grinding should be all it takes to upgrade a regular paperclip with Pinclip functionality. [Koncent via Spoon & Tamago]
