So while we are picking apart this list of " supposed " facts,
According to a little research, Scissors were invented by
Juan-Miguel di Sizore of Toledo Spain in 1494 See the story below

The Invention of Scissors

Scissors are, perhaps, the most familiar of all household implements; they are a tool that most of us use almost every day, without ever stopping to consider where or when they were invented, or by whom. Well, we at the museum are ever ready to right such a wrong.

Scissors were, in fact, invented in 1494 by Juan-Miguel di Sizoré, of Toledo in Spain. Sizoré was, by trade, a sword-maker, working in the high-quality steel for which Toledo is justly famous. He was a craftsman of the highest order, and brought many startling innovations to all aspects of the craft. His invention of scissors was, however, purely accidental.

He had been working under considerable pressure to produce a batch of twenty-four swords of the highest quality; the consignment had been ordered by no less a personage than Cardinal Torquemada, leader of the infamous Spanish Inquisition, and were intended for use by his personal bodyguard. The work had not progressed well; Sizoré was now a full two days behind, and was working feverishly to complete the order for fear of the consequences. The workshop was in chaos, with half-completed swords lying everywhere.

Sizoré hardly knew what he was doing as he rivetted the handle in place on the twenty-fourth sword. It was only when he picked it up that he realised that he had accidentally rivetted the sword to another, which had been lying beneath it. In a fury of frustration he grabbed the handles of both swords and tried to pull them apart, and serendipitously discovered the scissor-action when he inadvertently cut off the ear of Diego Mañana, his apprentice.

The invention ought to have made Juan-Miguel di Sizoré a wealthy man, but the unfortunate Mañana sued for industrial injury and, at the ensuing tribunal, was awarded all proceeds as compensation.

Sizoré died six years later, a bitter and broken man. He had, of course, become a broken man much earlier, when Cardinal Torquemada discovered that his order was two swords short. A man such as Sizoré is a fragile thing, and as Torquemada demonstrated so convincingly, easily broken.
