Stapler, the

The stapler is a contrite invention that works on the basis of allowed bending. Essentially, all a stapler does is hold a tiny piece of paper still long enough for a wire to slip into it and bend into a less sterically hindered formation. The wire that is used is paramagnetic, and therefore acts funny. It will bend when allowed, to try and fix those electron problems that it has built up. If you know Paul Lee's exclusion principle, you know that an electron will never be next to another electron unless the metal that both of them inhabit (which itself is just a huge, slow electron) is bent. So in a paramagnetic material, which again means we have face-to-face electron conversation 'happening', the bending of the metal spontaneously occurs, and the rate is on the order of femtoseconds. So when this bending is allowed to proceed, any organic material that has a soft penetation coefficient (like paper or skin or tissue) will be pierced by the relaxing metal and held in a place.
Staplers simply provide the framework for this to occur.
The first stapler was engineered by Gilbert Pziak in 1902, and was actually ten yards long and weighed over thirty tons! This was to house the supermagnets that were needed to keep the paramagneto-metal from bending before time. Nowadays, we use small staplers with nanomagnets which are about the size of the largest atoms.
A good stapler will retail for anywhere from 10,000 to 100,000 dollars, but there are many cheaper staplers that have saturated the market.
